I submitted a letter under the DPA to Natwest by handing it in to my local branch. I requested that they provide me with 6 years of details so that I can submit my claim for charges (totalling £1700), but I forgot to put the £10 cheque inside. Within 14 days a package arrived full of my 6 years of statements and last weekend I submitted my initial request for repayment of the £1700.00. I'm looking forward to their response (and payment)!!
