Product: Checking or savings account

On or about the XXXX of XX/XX/2021 I was texted a message telling me that XXXX XXXX XXXX was about to withdraw a payment of {$440.00} from my checking account using my debit card information from an older debit card that I had on file some 4 to 5 years previously. The message gave a number to call to cancel the subscription that was supposed to have been activated back then. So I called the number and the person that took the call told me that in order for me to cancel the subscription he had to pull up a special page for that and I told him that I do not have a subscription for XXXX XXXX and I had cancelled the subscription back then and never renewed and I now have XXXX, so he proceeded to the cancellation page and I cancelled it again on that page. He told me he could refund the money back into my account right then so he pulled up a page with my bank accounts and asked me which account did I want to put the refund in and at that time I asked him how did he get my accounts information and he stated that he got it from the debit card that I had supposed had used back then to start the subscription. I told him that since back in between then and now I've had 3 to 4 new debit cards issued to me. So knowing the amount of money I had in my checking account I told him to put it in my savings account so this way I could see that he had put it in because I only had {$55.00} dollars in my savings account and {$29000.00} in my checking account that I didn't want him to see. So proceeded to put it into my savings account and then he made a mistake and made it look like he refunded {$20000.00} dollars and he couldn't let his company that he work for know he made such a mistake so he told me not say anything about his mistake to anyone because he would get fired and he is married with 3 kids and a wife and he is the only one working to support his family. At this point he told me to withdraw the {$20000.00} dollars from my savings account and mail it back to him so no one in his company would know But I couldn't see that he was taking the {$20000.00} dollars from my checking account it was showing on my screen that he was putting the money into my savings account. So, after awhile I decided to check my other phone that was charging to see my balance and he said not to check my phone right then because it was going to take awhile to show up in my account so I waited a few minutes and checked the App on the phone and saw my balance was down to {$1600.00} dollars so I called the bank and asked why was my available balance down to {$1600.00} dollars when I had a balance of {$29000.00} dollars and that's when the bank representative told me that I had withdrew {$20000.00} dollars from my checking account and put into my savings account and then I explained to her that it wasn't done by me and I told her about the guy from XXXX XXXX was refunding money back to my savings account and she said that he was a fraud and he was taking the {$20000.00} dollars from my checking putting it into my savings account and that's when I filed the fraud claim but other transactions took place before I got to that point that XXXX XXXX XXXX  gift cards was involved too.
