Having bombarded by them so much I wondered if I am actually owed any PPI back.
However, having watched a money programme this week it seems like it's not difficult to do it yourself so considering companied want 30 - 40% cut tat seems a bit of a rip-off.
Just get in touch with a company like Experian and they send you all the info online of all your credit cards, loans, phone contracts etc. Only seen a sample so far as I'm awaiting PIN but it looks detailed.
Doesn't look too difficult to chase up though. Think they even have a sample claim letter.
