Hi
I've recently submitted 7 claims for ppi on loans , a credit card and mortgage repayment insurance . You can ask your bank for old statements or obtain a credit report which will give details of loans etc. Companies like Capital One have dedicated teams to deal with claims , and it's really easy to do it yourself without using a company who will charge a fee. There's a completely free online site called Resolver, which is endorsed by Martin Lewis who set up money saving expert. They have letter templates for most companies and it takes around 10 minutes to fill one in. The site sends it off, so no need to try to find the right address, and you get an email update . It's a brilliant service and well worth trying . Highly recommend
