This is part of Case number : XXXX which was supposed to have been resolved with credit reporting agencies ( as per letter we received from M & T ) but the issue has yet to be resolved ( it 's been 5 months ). We received a letter from M & T Bank stating they were going to resolve the issue with all credit reporting agencies. The negative mark is still on my wife 's TransUnion report even after took proper steps with XXXX to have the issue addressed. Per XXXX ... They contacted M & T Bank and their investigation did not result in removing the negative mark from XXXX credit report ( the XXXX report is unchanged ). I am including the original complaint inside this case because I was n't able to find a way to dispute or reopen the previous case. 
XXXX ORIGINAL COMPLAINT ==== My wife and I walked into the XXXX XXXX M & T Bank branch XXXX XXXX XXXX XXXX XXXX XXXX to close all of our M & T accounts on file ( for myself and my wife ). We clearly stated our intentions to close all accounts and move on from this bank. After a half hour or so, we had exchanged cash where applicable in order to zero out each of our XXXX accounts. The banker told us we were completely closed out. We left the branch that day under the impression all accounts were closed per our discussion with the bank rep whose name is XXXX. A few weeks later we discover my wife 's " overdraft line of credit '' was in fact left open ( against our wishes ) and was now showing a negative balance of XXXX {$60.00}. The banker only actually closed XXXX out of XXXX of our accounts ( left my wife 's " overdraft protection '' line of credit open, even though the checking account it was linked to was closed ). So we immediately call the branch and we 're initially told its not possible to close the line of credit without coming into the branch. My wife explained to the rep its extremely difficult for us to come to this branch as its not close to our residence. Finally the rep says she will close the account and mail us a bill for the remaining balance on the account ( telling us that they waived a late fee ). 3 weeks go by and we do n't receive anything so we call again. This time we speak with a third rep who tells my wife to mail in a check for XXXX {$30.00} which will close out the account and we 're assured the account will actually be closed this time. We leave for a one-week vacation and when we return theres a letter from M & T Bank which is dated 3 days before our previous phone call and states that there 's an overdue balance of {$1.00} which at this point is 50 days past due and that this has been reported to credit bureaus. Sure enough we check my wife 's credit report and now see XXXX delinquent account on her report. This is the first and only delinquency on her credit report and her score has already dropped by XXXX points. We 've spoken with the branch manager named XXXX who is currently researching the issue has told us he 's not exactly sure if this is the bank 's fault and can not promise a reversal of the negative reporting to the credit bureaus. We firmly believe if the first banker ( XXXX ) had simply closed the overdraft line of credit the first time we visited the branch ( as we had asked for and assumed had happened ) there would be no issue and nothing negative to report to the credit bureaus.
