I had no account info whatsoever – wrote to every bank and card providers I have ever had – just completed various forms and to date I am ….. wait for it 6k better off!
Had no idea I wasn’t paying ppi on loans and cards
honestly you don’t need any info – complete the enquiry forms, the banks will wrote back with account details they hold and whether there was PPI linked to the accounts. You write back or complete their forms on a compliant on the PPi and 4/6 weeks later you will be refunded your original premium, interest and compensation for the loss of money!
