I spent ages on the phone to them earlier.
I was meant to get my line activated (aka flick a switch) on the 4th july. I didn't hear from them and i assumed my line was active (before anyone points out that i could have tested it myself - i have hardly spent more than a couple of hours at home for the past few weeks!). I then got a letter from sky saying my activation date for my broadband has been pushed back because BT haven't activated the line!
I got on the phone to them the next day - they didn't know what had happened to the engineer originally but i had to re-arrange the date to the next week. I wanted the coming friday but after a lot of pestering they wouldn't do it. The engineer came round, tested the line and it was all fine. I had been given the impression on the phone that they had to do a lot of work in the property hence the need for a visit - clearly this wasn't true. I also demanded a refund of my activation fee but again, they told me to call up after the line was activated..
I called them earlier to demand a refund and i was told flat out that they could not refund the charge because of the work that had to be done. they said an engineer visited on the 4th but they couldn't access the property (this is despite me giving them my mobile number and explicitly stating that the engineer needs to call me close to the time - they didn't). I was then told i couldn't get a "missed appointment" payment of £10 because I had missed the appointment, not them. They also told me they sent me a letter to tell me i needed to contact them to re-arrange an appointment. This letter never turned up. There was also a massive flaw in what they were saying - the engineer who did eventually come round did nothing but check the line was OK at our end, so surely if no work ever needed to be done, wouldn't the line have been activated anyway without the need for the engineer to visit back on the 4th? They couldn't give me an answer for this.
Eventually after speaking to their manager they gave me a £10 refund for the missed appointment after they accepted there had been some miss-communication. They would not, however, refund the activation fee because the previous person was not on a BT service so they had to do work on the line. Carp. I'd pursue the matter further but having already spent the best part of 1-2hrs on the phone to them i've given up
