I know how you feel, a friend of mine told me I would be back to BT within 18 months. It is now 13 months and I have had nothing but hassle from day 1.
Apart from having an internet connection of anything from 28 to 750bps, which has now been resolved I now find I have no telephone service and judging by the amount of people that normally phone me, I haven't had it for approx. 24 hours.
Why can a company be so inept as this......
I'm not happy
