On XXXX XXXX 2016, I informed M & T Banking that there were several fraud charges on my account from an XXXX customer. These transactions were noted by me on XXXX/XXXX/16 and was reported on XXXX/XXXX/16. However, M & T Bank stated they would investigate the matter and informed me that they would give my money back in a few days. 
Five days later, on XXXX/XXXX/16, M & T Bank deposited the stolen money back into my account with the exception of XXXX transaction. I was informed they could not stop the other transactions from going through therefore they credited my account. When they credited my account I assumed it was the money that was illegally taken from my account on XXXX/XXXX/16 and thought nothing of it. 
On XXXX XXXX, I received a letter stating that M & T was going to reverse the credit and pull all funds from my account on XXXX/XXXX/16. I asked M & T Bank " Why was this draft or reverse credit taking place? '' They informed me that they never paid the illegal transactions that took place on XXXX/XXXX/16 because they did not receive the required paperwork from the third party. I then asked " If they never paid then why did they credit my account XXXX/XXXX/16? When I viewed my account on the XXXX, it clearly showed the transactions taking place ... this is the VERY reason I called them in the first place. However, when I viewed the account documents, the account showed no evidence of any illegal charges taken place on the XXXX. As a matter of fact the only transactions relevant to this issue noted was the credit on XXXX/XXXX/16 M & T had placed in my account. The problem with this is, if you see the credit on the account, XXXX would most likely ask why is there a credit? M & T could not tell me exactly why the charges fell off the monthly statements which would have have shown why the credit was on XXXX/XXXX/16. I then proceeded to ask why did you credit my account on the XXXX of XXXX for activity that did n't take place on the XXXX/XXXX/16? I told the bank " if you did not pay the charges on the XXXX/XXXX/16, then why the heck did you give me a credit making me think you were simply reimbursing me like you said you would on XXXX/XXXX/16? Now you want to reverse the credit back to M & T on XX/XX/XXXX/2016.This has caused total confusion and obviously documents have been changed or loss to benefit M & T XXXX I do n't understand why it would take 5 days to determine if you are going to pay a transaction or not. Yet on the 5th day and 5 days later you give me the same dollar amount which was originally illegally taken on XXXX XXXX! ( see amount below ) : For the record I called M & T on XXXX & XXXX XXXX and XXXX XXXX and tried to solve the problem. The M & T letter I received was dated XXXX XXXX, 2016. The # is XXXX. Each time I called and spoke to several employees the response was unacceptable. The last person I spoke with was XXXX who identified himself as 'XXXX the Manager '. 
Because of these transactions being reversed, this has caused undue stress on my entire family and home expenses. Transactions : All illegally withdrawn on XXXX/XXXX/2016 : {$510.00}, {$510.00}, {$510.00}, {$70.00}. The total amount M & T will reverse are the same numbers and amounts above. 
XXXX : Why did M & T credit my account on XXXX XXXX, 2016, when they did not pay the transactions on XXXX XXXX, XXXX? The bank could have just not did anything because I would of not have lost any money, that is, if they did not pull it from my account-right? It looks to me like I am being forced to pay for the illegally transactions, not caused by me, out of my pocket by allowing M & T to revere the credit. Also M & T could not and would not show that the illegal transactions on XXXX/XXXX/16 were not paid which is suspicious banking activity to me. All documents should available for view. I do n't see how the purchase of overseas plane tickets could be reversed! M & T could not show the illegal transactions on my account that happened on XXXX, but was glad to show the credits on XXXX/XXXX/16.
