Thanks very much for your help. I have tried to do it myself but when I asked Ford Credit for the account history they tell me that they have no records over 6 years old. What's my next step?

Ford Finance tell me that they have no record of PPI payments

because the account was paid off more than 6 years ago.

However a CMC tell me that for an upfront fee of £70 per claim they can get access to this information

without any paperwork or account numbers.

They call this fee a deposit which will be refunded on completion and suggest payment by credit card.

They then charge 25% of any subsequent compensation.

Any advice would be appreciated
