Extremely poor connection speed plus the line keep...

Question

Hi
I moved into a new build flat in Jan 2013, and had an outsourced engineer activating my phone line early Feb. When I first signed up to the service, the estimated connection speed was advertised to be 3-7 Mbps.
It's been about 12 months since the line was activated, and I've been suffering from 2 main problems which were never resolved:
1) Line dropping - the middle "Broadband" light of my BT homehub turns from blue to flashing yellow once every few hours every day. On a very bad day, it happens every 20-30 mins. I need to work from home sometimes and to connect to my company's VPN. The frequent disconnection of broadband has caused a huge amount of trouble in the last 12 months!
2) Very slow broadband speed - the estimated connection speed has always been advertised to be 3-7 Mbps. In fact, in the first 2-3 months after the line was activated, the average speed was 3-4 Mbps, but since last April the speed has remained around 1-1.5 Mbps, or 2 Mbps on a good day.
The speed seems to fluctuate a lot as well - I can tell from loading a YouTube video. Basically at all times it is impossible to load a 720p video properly. Turned it down to lower bit rates, it loads for a few seconds then stops loading at all. About a few seconds later, it continues to load again... so on and so forth.
I used to be able to use LoveFilm/BBC iPlayer streamed to my TV in the first couple of months, but now there is no chance of doing it at all.
With the combination of the 2 issues, I have complained to BT so many times but every time I was told that my connection speed was good, even though it is far less than the speed range I was advised when I first signed up. It has been extremely frustrating that it's almost the end of my contract but I still cannot get a stable broadband connection nor a reasonable speed that will load a YouTube video smoothly!
Below is the stats I've got from a speed test and from the HomeHub. Tonight seems to be a less busy night, so I will post the stats from another time when the issues are really bad.
The problem has been bothering me since I moved into this flat and I'm getting really desperate so any help is much appreciated!
Many thanks,
Will

Answer 1

if you cannot access the master socket and hence the test socket you cannot eliminate line noise caused by the internal wiring and if engineer finds internal wiring the problem then you will get charged £130 for call out
removing the bellwire is easy but really need to be the master as well - still all extensions will be a start  bellwire removal
