Well from my experience I can say, lucky you. You seem at least to have a working phone line at least.
For ending your contract I can tell you that this cost me several hundred Pounds and BT still wanted more.
And the best thing was they ended my contract a month premature and refused to switch it back on.
I got told I can not get my old contract back and have to take out a new one. So I got an email telling me
I am switched back on in a weeks time. When nothing happened I phoned in. Just to be told I am gonna
getting my line switched on in another months time. So they left me for more than a month without
a phone line and broadband. How does that sound?
So be warned if you try that. Make everything waterproof beforehand and document anything and
everything.
Towards your connection problem:
What does your Bitloading look like? Are you loosing the DSL line or the internet connection?
I had the exact same problem as well, got filters fitted and what not. Nothing helped.
Only when I insisted to have the equipment in the exchange checked they told me they had
checked it already many times but would swap the card just for the peace of mind.
And guess what. No problems at all after that.
Took me three different engineers and many visits to my site.
I am pretty certain doing that earlier could have saved them and me a lot of hassle.
