I received a {$2500.00} transfer via XXXX into my TD Bank account on XX/XX/XXXX. The transfer was clearly either sent to me in error or as part of a scam. I noticed the transfer on XX/XX/XXXX when I tried to use XXXX and my account had been locked. I called the bank and they pointed to the {$2500.00} transfer which I confirmed to them was not anything I was expecting and reported it to them. However, the only information they could provide me was that the person sent to my via my email address. I had a name that was noted on the transfer but no other identifying information and TD said they could not do anything to assist transferring it back ( and XXXX itself is unreachable by bank users ). 

I spent several hours on the phone with various reps from TD over the next several days explaining that this amount was sent in error by someone and I would be happy to return it but had no way to do if they could not assist me and also said there is no reason that my account should be blocked due to someone sending me an erroneous transaction especially if they would not provide any assistance in figuring out how to contact the person since the transfer record only contained a name and no other info. They ultimately said there was nothing they could do to open my access or help me in any other way. 

On XX/XX/XXXX, one full month after the transfer, the person who send me the transfer finally reached out me over email ( which he would have know as he mistakenly sent me the transfer using my email address ). I told him I'd be happy to return the money as I had been trying to do since I received it ( and we agreed minus {$500.00} due to the hassle I encountered losing access to my ability to transfer money and the time spent resolving it ) but I would only do so through the banks as there are many scams out there with people sending money through XXXX or other manners and then asking to be repaid via check or some external system. However - due to his having reported this as some sort of " fraud '' as opposed to him having immediately contacted me to ask me to return the money - I can not XXXX or wire money from my bank accounts as that ability has been frozen. 

My bank says they can not restore access until the report has been cleared. He tells me his bank says they have nothing to do with this anymore so we are at a standstill and I am getting progressively harassing letters from the sending demanding that I return the money to him by check or some other transfer like XXXX XXXX which I refuse to do as ( XXXX ) I do not feel that protects me from some sort of subsequent action by the banks finding a way to reverse the initial transfer down the road as they would not have any record to show that it had already been repaid and ( XXXX ) I would still be actually damaged by not having my full account access restored due to his actions of having reported this in a way that led to action being taken against me. 

It has been impossible to speak to anyone in TD with decision making authority on restoring my access to XXXX which would solve this problem immediately. The highest level I could reach personally simply tells me the decision makers declined to restore access. 

I would greatly appreciate assistance with this as I am in a no-win situation here. I'm either dealing with a potential lawsuit or a potential scam and the bank really should be the ones investigating this and not leaving it to it's customers after having taken away the one method that I could have safely resolved this.
