I was initially turned down by my credit card company. However, I wrote a letter before action pointing out that the basis on which they made their decision was incorrect. I returned from holiday to find they have now upheld my complaint and will send a cheque out to me shortly.
So to those of you thinking of claiming PPI do it yourself just google PPI questionnaire. Some banks etc haven their own. Also if they initially turn you down and you disagree with their decision then write back asking them to rethink giving your reasons why. I am getting a small amount returned to me but it is mine. They usually take the tax off at source, as they are in my case but they don't always.
Has anyone else had an experience of claiming PPI good or bad?
