Have already sent a letter to nationwide regarding charges, but have just found this site. I want to reclaim £327.50 in Returned DD's on my account. Found this figure by checking through all my previous statements. So may miss out contacting them for details of charging and send the first letter asking for repayment. Am also worried as have my mortgage with Nationwide and not sure how this will affect me. Anyone withe any suggestions. Cant believe how many people are claiming money back and the sums involved. SCAREY!
