Back in 2008 BT fecked up our 'home move' BIG TIME and with Dan working at home it was really bad. They promised us compensation which we never got.
So as soon as I left working for BT I moved to Talk Talk, and told BT I was leaving cos of the terrible service and the fact the never paid us compensation despite me chasing a number of times.
Then 2 weeks ago I had a Debt Collector come to MY HOUSE
for £113 of cancellation charges. She was lovely to be fair and I showed her all the emails and she said she'd send it to BT and say we cant collect money when its in dispute.
So again I contacted BT but they reckoned all the records from 2008 were archived and they couldnt even find the files in the archive!
Luckily I had copies of all the emails and sent them to BT and the Debt Collector ... and now, 2011, they have have written off the £113 charges in exchange for cancellation fees - isn't that nice!
Had I not had proof (the emails) they would have told me to do one, and I'd have been £113 poorer!
Its even more important if you change your email address - make sure before the old one expires/forget the password etc that you get copies of anything important!
