Product: Checking or savings account

On XX/XX/XXXX, I was approached by a stranger ( XXXXXXXX XXXX XXXX XXXX XXXX XXXX XXXX around XXXX, XXXX ) around my house when I was on my way to work. He told me he left his phone on XXXX and asked me for help. I used the XXXX app ( which will hide my phone number ) to call the number he provided, but no one picked up. As I tried to walk away, he grabbed my phone and started typing into it. I asked if he is texting the driver and he said yes. However, I was really suspicious because his fingers keep swiping and he seemed to be very nervous and distressed. I told him I need my phone back because I was late for work but he kept telling me the driver was replying and he would circle back in couple minutes. 
Feeling unsafe and uncertain if he was armedI am a woman and was aloneI chose not to escalate the situation ( stand behind him to check what he was doing on my phone or grab my phone back ). After approximately five minutes, he handed my phone back, said the driver had arrived, and quickly ran away although I did not see a car nearby. On the way to work, I immediately checked my accounts and found an email from XXXX to confirm a {$3000.00} transaction on XXXX. I immediately blocked it and went into my XXXX account and found out there was a {$2500.00} transfer to " XXXX XXXX ''. 
I immediately contacted XXXX, XXXX, and the police department to report the fraud. XXXX told me there was another transaction of {$45000.00}, which was denied due to insufficient fund ( total : {$2500.00} + {$3000.00} + {$4500.00} ). I requested XXXX to freeze the receiver 's account so he would not have access to the fund and the agent told me this is what they usually do during investigation. XXXX assured me they would freeze the recipients account during their investigation. However, I later received a misdirected email meant for the recipient stating, " We are happy to keep this disputed amount of {$2500.00} USD available in your XXXX balance as we continue to resolve this case. '' This suggested that the account was never actually frozen. 
Chase initially credited my account on XX/XX/XXXX, but later reversed the credit on XX/XX/XXXX, claiming XXXX had denied the claim. When I followed up with XXXX, they said the case was still under review. 
Throughout this process, neither Chase nor XXXX contacted me for additional information ( XXXX customer service repeatedly assure me that their claims departments would reach out within 10 business days ). On XX/XX/XXXX, I proactively submitted my police report to both institutions using links provided by their customer service teams ( not their claim department ), who also didn't know why no one had ever contacted me. 
Later that day, XXXX informed me I had " lost '' the case because I filed the dispute through my financial institution. I suppose they meant because the money came from my checking account not from XXXX balance, it is not their responsibility. However, this reasoning feels both unjustified and misleading, as the source of the funds should not negate their responsibility to investigate the fraud properly ( not to mention a lot of people also encounter privacy breach with XXXX because of their faulty system design ). 
Furthermore, had Chase sent me transaction confirmation emails for each unauthorized payment, I could have blocked all transactions, not just the {$3000.00} one. I haven't heard back from Chase since submitting the police report but I hope CFPB can intervene to ensure my case is fairly reviewed, my funds are recovered, and appropriate measures are taken to prevent others from becoming victims of similar fraudulent activity. 
This experience is extremely frustrating and discouraging as I was just trying to be a kind and helpful person. It is important for this person to get his legal consequences as this amount of money already constitute a felony, and not just a crime. From how quick that person was able to do 3 transactions within 5 minutes, he has obviously done it several times. If that person can get away with the money, this is basically encouraging crime and more people will fall victim to him.
