Fine until I moved house.
It took 14 phone calls 2 emails and 4 letters to acheive this though. They don't seem to answer any letters though.

I was disconnected from broadband for over a month and from there phone calls for 3 months, each time I called I was told it would take 10 days to fix and I should call back then!

During this time I was charged double at both addresses.

When I was eventually connected it was to the wrong package.

When I cancelled the service after the 12 month contract, they disconected me early and charged me ?70 for breaking the contract.

Customer services take about 20minutes to answer.
