The following information is provided by XXXX XXXX customer oXXXX XXXX XXXX XXXX. This COMPLAINT is addressed to CITIBANK. 
This complaint is a result of a wire transaction that I initiated from my personal account at XXXX XXXX XXXX on XX/XX/2021. I had just gotten out of the hospital recovering from the lingering effects of XXXX  and XXXX. My business partner in XXXX requested a wire transfer transaction of {$40000.00} as payment for a current business arrangement. I have sent many wire transfers to this individual in the past and proceeded to initiate the wire via my XXXX XXXX XXXX online banking platform. The sending bank is XXXXk XXXX XXXX, and the receiving bank is Citibank. I inserted the requisite wire transfer information on the XXXX  XXXX XXXX XXXX banking platform and knowingly admit I may have transposed the beneficiary account number. I received a confirmation from XXXX XXXX XXXX and assumed my wire transaction had been processed as usual and without any complications. My suspicion of my transposition error of the beneficiary account number became a reality the following day when my business partner called and inquired about the {$40000.00} transfer, indicating he had not received the money in his account at Citibank. I promptly called XXXX XXXX XXXX customer service line and asked what happened to the money transfer I initiated the prior day. I informed the bank representative my business partner had not received the funds and I wanted to know what happened to my money that was taken out of my account? I was transferred to several individuals within the XXXX XXXX XXXX customer service area and was told they would open a case and investigate. I waited to hear from someone from XXXX XXXX XXXX when I finally received word that after their 45-day investigation period Citibank still had not responded to the XXXX XXXX XXXX XXXX for information XXXX therefore the case is closed. I continued to pursue my quest for information on the disposition of my money and time and time again I was told Citibank is not responding and there is nothing further that can be done to locate my {$40000.00}. I ask the questionHow can two big banking giants like XXXX XXXXXXXX XXXX and Citibank just disregard a consumer inquiry of funds that were taken from the consumers account ( mine ) and not provide any explanation. How can this happen? Why should XXXX XXXX XXXX or Citibank not be held accountable for the disposition of my funds? How do I know the funds have not been misappropriated or possibly still sitting in a bank holding account? I am a consumer that can not afford to simply lose money that I wired in good faith. Either XXXX XXXX XXXX or Citibank should have the resources to provide me with some answers as to the whereabouts of my funds. 
The original date of my transfer is noted on my checking account statement as XX/XX/2021, to date I am still in limbo and my questions as to the disposition of my funds have been ignored. XXXX XXXX XXXX is blaming Citibank and Citibank is not responding to any requests of information. Where is the oversight within these institutions? 
I have filed a complaint with the OCC and the Federal Reserve in hopes of getting some answers as to my missing money. I finally received a response on XX/XX/2021 from a representative at XXXX XXXX XXXX informing me that the bank has repeatedly attempted to contact Citibank and since they are not responding to any requests of information, my case is once again closed. 
Who is the responsible party here for locating my funds? Where is the {$40000.00} that was taken out of my account? Why has Citibank been afforded the luxury of non-response to any XXXX XXXX XXXX requests? I personally find it hard to believe that the random numbers I may have input through an online banking platform can be credited to someone's account at Citibank. Where is the accountability within the financial industry to protect the consumer? There are still many questions here that require answers. I believe I am due an explanation as to the disposition of my money. XXXX XXXX XXXX lack of caring and apparent inefficiencies have made my life very stressful ; {$40000.00} is a hefty sum of money I cant afford to ignore and just accept XXXX XXXX XXXX response that my case is closed. I wired the money out of my account in good faith and XXXX XXXX XXXX has put me in a very difficult financial situation. I would appreciate any assistance your banking division could provide. XXXX XXXX XXXX and Citibank need to accept responsibility for this situation and provide me with some answers. Additionally, I have never received provisional credit during the XXXX XXXX XXXX investigation process and the ongoing quest to recover my missing funds has taken a toll on my financial resources. Thank you for your consideration in looking into this matter.
