They really helped me. I had some paperwork and the original loan agreement reference. I obtained a copy of the credit agreement from the bank, you pay £1 to get this, but there's a letter you can use from the website. I filled in the Questionnaire (provided by the site) send a copy of the agreement and a letter asking the bank to review. It took less than a month all in.
