Dear Sir or Madam, I filed this complaint that I faced a check fraud and I believe that the Chase bank is liable for my loss. Because from my point of view, the bank is liable for accepting a check that has been forged, altered, or improperly endorsed and the bank teller did not perform or exercise ordinary care and diligence in handling the transaction, I will elaborate the whole things as following : On XX/XX/2019, I wanted to sell my XXXX watch to an individual and he committed to offering {$11000.00} cashiers check to buy this watch, on XX/XX/2019, We met in Chase branch located  in XXXX XXXX XXXX ( XXXX XXXX XXXX XXXX XXXX, New York, XXXX ), in order to have my trust, this guy was along with me to deposit the check around XXXX XXXX. Because it was my first time to have the Chase cashiers check with large amount, I double confirmed with the bank teller if this is the Chase cashiers check and the check should be ok to deposit, the bank teller gave me the positive answers so I trust her professional, however, finally it turns out that it is obvious fake check because the account numbers in the check did not exist at all, in this regard, it has shown that the Chase bank did not exercise ordinary care and basic diligence in handling the transaction. 
Also, after deposited the check, the bank teller gave me the receipt and told me this fund will be available after four days, however, I just wondered why the wrong account numbers existed in the check but not any text, message, email or even a phone call alerts reached out to me ; afterwards, the weird things occurred, as a sapphire banking customer, I called XXXX at XXXX XXXX  on the fourth day-XXXX XXXX, 2019, however, the representative told me that the Chase bank still holds the check simply because it was inconsistent activities, in the meantime, I asked her so have you collected the money from the paying bank? the answer from the representative was yes., it was the second time to show that the Chase bank did not exercise ordinary care and basic diligence in handling the transaction. 
Thereafter, I found there was message sent to my email box and it said there was a letter and I should log on the Chase official website to check, and it shows that my fund will be delayed to XX/XX/2019 but at that time, there was still nobody from the Chase bank told me the check was a bad check, at XXXX XXXX I called the XXXX and reached the customer services, this time the customer services told me that it was a bad check, I was totally confusing, and the weirdest things followed by after few hours, the {$11000.00} funds became available in my Chase apps and it can not see any difference from the regularly available balance. 
For the security purpose, I did not touch this fund and went to the closet Chase bank directly which located in New Jersey at XXXX XXXX and the banker in that branch confirmed it was a fake check and recommended to file the police report ASAP ( that guy who was along with me to deposit the check did not reply or answer my call at that time ), I followed his instruction and filed the policy report thereafter, I went back the Chase branch located in World trade center which I deposited the {$11000.00} check, the branch manager was also confusing with this issue, the fund credited to my account and showed it was available but the check was a fake one, if that is the case, where is this money from? I doubt that the Chase bank system and staff professional are not both perfect as advertising, I mean that from the beginning nobody noticed me that the check may have some problems and after four days, the first representative even told me that the Money has been collected from the paying bank, as if I did not call XXXX, I would think everything should be ok ( not any alert, bank teller as well as the representative confirmed and the available balance {$11000.00} was shown in the apps ) until XX/XX/XXXX or maybe later. 
From the stated above,, Chase bank in XXXX branch should be liable for accepting a check that has been forged because the Chase bank did not exercise ordinary care and diligence, which brought such a big loss for me, a high-value customer, I am absolutely the victim and I believe the branch should be required to reimburse the loss ;
