BAD SERVICE

I am rather annoyed - Early this week we got a call from your call centre to upgrade our ADSL line from a 4Mbits to a 10Mbits, I advised them that I had some concerns as I know our area cannot receive those speeds, (I was assured that this was not true) and that I was happy with our uncapped 4Mbits. They very quickly phoned my husband to get approval before I could tell him not to upgrade, but assured him we could cancel and revert within 5 days should we not be happy. Since the upgrade my ADSL slowed down considerably - instead of picking up speed as promised. AND to add insult to injury - I now barely have any speed whatsoever since the line has been \limited due to usage". And then to top it all off - when I phone to cancel the upgrade and revert back to my old line - they tell me...\""Our system is down"
