Horrid Infinity experience

Question

I had Infinity installed a few months ago and it has been nothing but a nightmare. Right from day one and is still a nightmare, here is my story about how shambolic BT have been.
Firstly the engineer who fitted my filtered face plate ripped out all my extension wiring from the faceplate and then could not put it back. He gave no explanation, fiddled with it for about 45 minutes randomly guessing which wires went in which punch down on the back of the socket, but could not get my phones to work again. I do not think he knew what he was doing, probably some contractor which has only been trained to activate Infinity.
Phoned BT to complain, as soon as he had gone only to be told I would be charged something like £100 for them to come back out and fix it. It was their staff that caused the mess, literally minutes earlier. How does that work, customer pays for inept engineer work? I obviously refuse their offer to bill me to fix their own mistakes.
IN ADDITION... The Infinity connection barely worked, sometimes it dropped sync and would not re-connect for hours, lights just flashed on and off. When it did connect I had a pathetic 2Mb upload and 4Mb download.
Phoned another department in BT to complain about this, going through the stupid automated options again, until finally ending up in the same call centre to be told that this is operating within spec.
Another two weeks go by until I had some time off work and I decided to fix what I could myself. Reconnected my phones all back up to the back of my face plate myself, working perfect. Decided to investigate the internet connection. I knew the 'engineer' had done something dodgy here also as the incoming drop wire looked a lot shorter than it did before. Remove faceplate fully from the wall and discover the 'engineer' (laughable to even call them that) had decided to tie the incoming drop wire to the faceplate in a double knot at the back of the socket. I know he did this as previously the wire had some slack and ran along the skirting board nice and flat and even to the socket. Carefully undo that. Reconnect it all back up and internet speed increases to 3Mb upload and 6Mb download. Not the success I was hoping.
Estimate given at sign up was 60.2Mb download and 20Mb upload. Ring BT again, told again it is within spec. I persist and have an engineer come out. I am warned by the Indian call centre and I quote 'this could cost up to £100'.
Engineer arrives 3 days later, says the faceplate is faulty. Replaces faceplate but speeds remain unchanged, he then performs other tests and discovers that a wire incoming is damaged and actually states 'It looks like at some point it had been severely bent'. I tell him yes that was your colleague who came to install my Infinity who decided to tie a knot in the incoming drop wire.  He denies that any other engineer would tie a drop wire in a knot and walks off to his van. He then proceeds in replacing the cable.
Nearly two hours after he first arrived everything is done and it is the moment of truth. Powers on the modem, looking good it at least connects first time now. I plug in my laptop to the hub. At this stage he starts looking at his watch and says 'Right all should be fine now' and he starts to try to leave. I tell him 'oh no no no, lets test it before you run off'.
Run tests at speedtest.net, no change. His attitude now is becoming quite a bit moody, walks out to his van again actually swears under his breath quietly (I still heard it) as he crosses the road to get to his van.
Comes back with another bit of gear, plugs that into the socket and this confirms the speed is still 6Mb download and 3Mb upload.
He then trys to phone some automated thing to get the line reset, only for the automated message to say something along the lines of 'unable to process request at this time'. He slams his giant handset done on my window ledge now fuming. Says there is nothing I can do and leaves.
One week later I get my bill in. I have been charged in excess of £160 for this "work".
Phone BT again to complain, told again everything is fine and the broadband will rise on its own accord within a week, told I can not have a refund as it was 'critical work' that needed to be carried out. Er yes it was critical because your original engineer damaged things and it still is critical because the second monkey could not fix things properly.
Three more weeks go by and phone now develops a fault and is noisy. OH JOY!
Ring BT, am shocked they actually admit it is a problem and automatically schedule an engineer. I query "am I going to be billed again" to be told "No sir, it is a fault external to your property at the exchange of cabinet".
Two days later I see the engineer at the bottom of my road at the cabinet. He is there for about 45 minutes, once gone phone line is clear.... Hooray they actually fixed something I think.
Aprrox another week later next months bill arrives and guess what...... Oh yes you got it right, ive been billed again. Call centre inept again, lied to again. Another £85.40 for this work.
Phone and complain again, support worker looks through the computer, apologises but says that the charge will remain incurred.
I query my broadband again which is still stuck at 6Mb down 3Mb up. DLM has done nothing to it even after all their "REPAIRS" and they offer to send another engineer. I obviously after the last £160 bill for "cough, splutter" broadband fault repair work decline.
So there you go BT the communications company that leaves you with no phone extensions working, wants to bill you at every opportunity, Calls "Superfast FTTC" 6Mb down and 3Mb as perfectly acceptable.
I would complain more to them and keep getting them to send engineers but I can not afford it. Monday morning I am off to Virgin, paying off the remainder of my BT contract and then rather than try to communicate with them filling a small claims action.
To think I once had shares in this shambolic mess of an organisation and have been a customer for over 30 years and thought they were an honest decent firm now just seems laughable.

Thank you all for the replies.

Are you BT staff? If so is there another way to contact you directly as i do not trust giving account or personal details to anyone on the internet. I will not even shop online so no matter how many assurances i get you are who you say you are, unless i know that im not handing out my phone number, account number and anything else im likely to have to provide.
If you look in to this problem how long is it likely to take for my broadband speed to be increased to anything near the estimates i was given?
If an engineer has to attend what assurances can you give me that i will not be billed any further for any other work?
How long is it likely to take for you to look in to what i was charged and have this refunded?
I have been fobbed off for months, billed when told i would not be and lied to already so forgive me if i am not very patient. I do not want to wait and currently have total and utter distrust of anything BT tell me.
@Paradox
Yes the Virgin visit is an actual appointment for Monday. Do you know what the charge will be if i cancel the installation?
Yep no idea how they can get away with charging me for work at their cabinet and not in my home or why i was billed for the home visit to fix broadband but in return just got a grumpy, swearing engineer that solved nothing at all.
Perhaps if Paddy can explain what those charges were likely to have been for in the first place i may have more trust and cancel the Virgin visit.  Otherwise no ill be glad to be gone from BT and to Virgin, file the small claims on Monday also. To be honest the deal i have been offered for 120Mb from Virgin even if BT could now put my connection right is pretty good, it would take a lot to convince me to give BT yet another chance. Horrid experience.
