Slow Broadband after 21CN Upgrade?

Question

Before my scheduled 21 upgrade my download connection has been rock solid at 8000K for several years.  My whole recent experience with BT has been very disappointing and I hope you can throw some light on a solution.
So Far:     
My Equipment:  BT2000 Faceplate, RJ11 to BT Homehub 1010, 1 Extension fitted (No Bell wire Connected). 
Problem 1. Now resolved.  On the day of my appointment the engineer connected my dial tone and broadband to someone else’s line in the next village.  The fault call centre insisted the fault could only be in my property as the line tested OK and I would have to accept the possible charges.  Despite my requests for them to despatch an engineer to the exchange as it is more than a coincidence that my dial tone disappeared at the same time as my scheduled changeover they insisted I have an appointment.  The fault was cleared in the exchange by the visiting engineer.
Problem 2.  Now resolved. The engineer did not remove the call divert on my line and I missed my incoming calls for several days as my calls were diverted to a random number.  I tried #21# and this did not work, so I contacted BT again.  They informed me they could not remove the divert because they had not put it on. After investigation #61# managed to remove my divert.  When I asked why it was not removed when my line was fixed I was told that I must have put the divert on myself as it was done by someone with access to my line. The whole point that my line had been connected elsewhere was totally alien to the call centre worker.
Problem 3.  On going
After 14 days of Mediocare performance I was connected much slower speed than my old connection and as my profile was 4000k this is only half of my previous performance. (See Below)
1. Best Effort Test: -provides background information.
Download Speed
5959 Kbps
0 Kbps
4000 Kbps
Max Achievable Speed
 Download speed achieved during the test was - 5959 Kbps
 For your connection, the acceptable range of speeds is 1200-4000 Kbps.
 Additional Information:
 Your DSL Connection Rate :4603 Kbps(DOWN-STREAM), 1251 Kbps(UP-STREAM)
 IP Profile for your line is - 4000 Kbps
The throughput of Best Efforts (BE) classes achieved during the test is - 16.4:29.53:54.07 (SBE:NBEBE)
These figures represent the ratio while sententiously passing Sub BE, Normal BE and Priority BE marked traffic.
The results of this test will vary depending on the way your ISP has decided to use these traffic classes.
2. Upstream Test: -provides background information.
Upload Speed
873 Kbps
0 Kbps
1251 Kbps
Max Achievable Speed
>Upload speed achieved during the test was - 873 Kbps
 Additional Information:
 Upstream Rate IP profile on your line is - 1251 Kbps
So I call BT again and after I have established that the only changing parameter is the new 21CN upgrade I am promised that a request will be passed to the engineers to increase the profile........  The result is that they just reset my profile, so once again my speed fluctuates for several days from a virtual stop to slow.
It is now six days since reporting my slow speed problems after receiving several calls from BT to ask me if my speed has improved, I am finally a broken man today. 
They insist that I have a broadband boost engineer, before I accept this, I ask several questions and failed to get any acceptable answers..
What is wrong with my broadband?  You have a fault in the property (change the record!!)
Why cannot you tell me the speed I am connected at.   You cannot WOOSH test me?  We cannot tell, we have to call you
Can I speak to the engineers?  You cannot Sir
Can I speak to your Boss?  No, why would you want to do that!
What have you done in the exchange to fix my fault?  We have changed some things
Do you thing it is acceptable to still have slow speeds after twenty days?  That's why you need a boost engineer
What are you going to do differently from all the other people I have spoken to to resolve my issue.  Nothing
So with no other option I accept that an appointment will have to be made again.  I am offered an appointment in the week, when I explain that I have business appointments and that I need a weekend appointment I am told none is available or would be available.  So I agree to a Monday appointment.  After the call I get a text to say I have an appointment has been made for Thursday!  So I have to call them back and ask for the appointment I have been promised and I am told it's a simple and easy mistake to press the wrong button, it happens quite often!!
I since read here that it may help to upgrade my homehub, so why have they not sent me a replacement days ago?

I know there are more important things going on in this world.  But my work, my ebay, my shopping, my banking, my social sites etc. all require bandwidth and to have it taken away disguised as an upgrade obviously upsets me.  I am shocked at the complete lack of communications, and the inability to listen and understand your customers.  What is the point of a call centre that can do NOTHING outside their script to help!
Solved!

Answer 1

Not sure why my profile is still changing and why I was disconnected today, probably the call centre doing another line test.
