oh right thank you. I shall just send the one letter with the one postal order and see what i get back thank-you for your help

hi all i was wondering if some one can help me. I am now sorting out the paperwork i need to reclaim my bank charges back from natwest as some days they are charging me £210 in one day and £35 every other day. I have sorted out my sar letter but i have two accounts so i sent the one letter with the two accounts or two letters (one for each account) both with £10 each in them or £10 between the two?
