I formerly held an account with this creditor for ordering mail order merchandise. I ordered one item and paid upon receipt. When beginning my credit repair crusade I noted the account was listed as charged off. I immediately sent a copy of the cancelled check, and noted recently the creditor chagned the reporting to Paid charge off - although the account was paid well before charge off. Today I receive a letter from Seventh Avenue regarding my dispute of this reporting: "We are writing to you in reference to your recent credit bureau dispute. At this time we are requesting that you send us a signed letter of dispute so we can proceed with our investigation." I feel that filing a dispute with the credit bureau should suffice. I don't think they should be asking for a second written dispute with my signature. Any theories on this? Should I ignore the letter?
