Out of curiosity, did you contact your bank or lender directly, or use a third party?
I am only asking, because I think that some of the fees charged are a bit extortionate. Was it an easy process if you did go straight to your bank?
I used to work for barclaycard a fair few years ago. Contact your bank direct. All a PPI company does is get you to fill out the same forms the banks do and charge you for it. Absolute opportunistic (legal) scammers.
