I have been on the 20Mb broadband since it came out in my area more than 12 months ago.
The maximun speeds i have been getting in that time have been around 13-14Mb and working nights and using the net at 2-4am this obviously isn't a 'busy network' issue but as it was a lot faster then previous and the 'up to 20Mb' statement I didn't bother about it.
Anyway, since a couple of weeks before xmas to present I am only getting between 5-9 Mb at any time of the day.
After browsing a few of these posts and noticing many getting 18-20Mb I realised it was time to phone them up.
I called them last night and after going through some tests was told they would call me back, which they never did!
I called again this lunch time, and again we go through all these tests and again told they would call me back.
This time i was called back. I was told the modem I have installed isn't up to supplying 20Mb and they would be sending me a new one in the post.

Hang on a minute!!!

I have been paying a premium rate for a service that wasn't even available to me ?

I phoned them back to complain and after a few attempts i got hold of a local (Scotland) person. After explaining all i get is 'I'm sorry but there is nothing we can do about it, we cannot pay compensation that far back'

Am I asking for too much here ? Am I being treated unfairly ?

btw - my modem is a Ambit Cable Modem
