I had been without a phone line for two weeks. I rang BT to ask for some compensation and was offered £8.29 - the cost of 2 weeks line rental. What a joke! I have had to use my PAYG mobile for the whole of the 2 weeks and racked up quite a sum. Also nobody was able to get through to us and the 1571 message box was full after 2 days, so for 12 days no-one could leave a message.
When I asked to an increased sum, I was told that I would have to request a "Financial Loss Pack", although they couldn't send me one out, as their systems were down, so I would have to ring later in the day and order it. Apparently, I will have to provide receipts etc for all the phone calls that I have made from my mobile.
Due to BT's incompetence, I've been without a phone line for coming up to three months. I was offered £25 as a "goodwill gesture" I told them this insulting. Haven't heard any since. So much for BT customer care!
