16 days and still BT can't reset my IP Profile!

Question

After getting one of the Hub 2.0 Type B in March I have been until June fault free. Gone are the constant random disconnects and the annoying flashing orange broadband light.
June 9th 2010 I rang BT and renewed my Broadband contract for 12 months. Was on Anywhere package but cancelled the BT Mobile and went to the unlimited Option 3, with the discount and saving from cancelling the mobile its down to £19.99 a month. 
June 10th 2010 and thats the end of my constant 6 - 6.5mb download speed. IP Profile is down to 2000kbps. I ring the Broadband Helpline and its the usual plug into the master socket, change your filters etc etc etc. Then without even asking I'm put through to a floor manager. He checks my account and I ask is this anything to do with my broadband renewal the day before? Line goes silent. Apparently work is being carried out at my local exchange, everyone in the areas speeds will be a lot lower than normal but it will be completed by midnight on June 22nd. He'd personally call me on June 23rd at midday to check the speed has recovered. They carried out a line test and all came back as being fault free.
Asked a few local people connected to the local BT Exchange and funnily enough they have no Broadband speed reduction.
23rd June midday comes and goes, no call. I ring the helpline, there is no floor manager by the name I was given! Theres also no notes on my account from 10th June hence no call back. That's the next hour of my life gone down the drain having to explain everything again. I ask if the work at the local exchange has been finished. What work comes their response. So thats 13 days waiting for nothing. I'm told that my line speed is actually 5.6mb but when I explain the IP Profile is 2000kbps I'm put on hold again. Now onto another supervisor and re-explain yet again.  A line test is run and now 3 faults are found. I'm told that an engineer is needed and I'll be called by that department shortly. 2 hours later engineering team call. All the faults have been fixed, its a BT Network fault. IP Profile has been manually reset to my original 7150kbps and within a day all will be fixed. I'm told the case will remain open for 5 days, any problems just ring the normal helpline number. Within minutes my IP Profile is now down to 1000kbps. So much for improving things.
25th June and still IP Profile of my line 1000kbps. Needless to say its a nightmare trying to do anything at all online. Once again I ring the so called Broadband Helpline. Spend ages explaining it all again. I'm told my IP Profile will be reset again as apparently its not been done and someone will call back in a few minutes. They indeed call and assure me its all fixed. I wait an hour (supposed to have taken seconds to fix) run bt speedtester and yup IP Profile for your line is 1000kbps. Another call, another excuse as to whats gone wrong, another supervisor and another line test, yes now apparently lines faulty again. So engineer booked for next day Saturday 26th June. I explain I've made arrangements and I'm out all day, I'm told if I'm not in I'll be charged, I asked about changing to a different day, not allowed you gotta take what your given. Thats my plans for Saturday out the window. I'm told without doubt whatever the problem is the engineer will fix it.
26th June engineer arrives. He's been given no information about whats wrong. I explain it to him and he tells me if its the IP Profile thats the problem he cant do anything as hes just there to make sure the line for the broadband is working. IP Profile is sorted out by Internet Service Provider (BT). The bungalow I live in is pretty new and the master socket is outside. Apparently all new builds now have no master socket inside the building its all outside in a little grey box. He connects to the master socket and gets 5.6mb download speed. Tries inside and gets slightly less. Fair play to him he checked every single telephone socket and took the wires out and re-connected them. There were some spare wires so he put a master socket inside and plugged directly into that. 5.6mb download speed. Connected my Hub and ran BT Speedtester.

He tells me when BT ring once he's gone tell them to reset the IP Profile. He explained how I can get over 5mb but until BT change my IP Profile 1000kbps is the absolute maximum. BT call, I ask them to reset my IP Profile. No that can't be done, an engineer needs to come out and do that. They'll ring back with a date and time.
They ring back, we've spoken to engineering department and we can reset it. It'll take a maximum of 2 hours. This was at 5pm. They told me not to use the internet or hub until 7pm. Then press the restart button on the hub and all will be fixed. They'll call to check too. Did what I was told, then ran another speedtest and get the same results as above. They call back, its all been fixed! I ask are they sure I'm still getting the same IP Profile of 1000kbps. Low and behold oh its not been reset yet again! Now I'm told theres faults on the line but I can get 5.6 download speed. Yes i can, but not until they rest my IP Profile which is limiting my broadband to 1mb! I ask what happens now? Gotta pass it back to engineers to arrange another one to come out. I asked what the line faults were but he refused to answer. 
16 days and still no closer to getting anything fixed. Apparently its in the engineers report which they have been sent to that my IP Profile needs to be rest but apparently that is something which BT are refusing to do.

Hi and thanks for your reply. 10am today yes sunday and the 3pm callback is 5 hours early. Myself and the rest of the people in the house are woken by BT, then annoyingly when I answer the line goes silent and the call is ended. 
The noise margin is a weird one, some people say that mine means I'd have a slow broadband speed but then I actually have a decent speed with the noise margin what it is.
Anyway good news, this mini war with BT looks like its finally over.
