I filed a claims report on the phone with Wells Fargo fraud, XXXX, and for the check. I have also filled out an FBI compliant form and a form with XXXX. Unfortunately, they are closing my account down and this situation falls underneath what Wells Fargos considers a scam and yet I haven't received anything. They sent me a {$400.00} dollar credit so I thought the check was good. Below is the situation. 

I work for XXXX XXXX Im an XXXX XXXX XXXXXXXX so I do this in XXXX and im just starting out. so I got a message on XXXX saying hey my uncle is moving to your area and it said this person was located in XXXX you can see their general location as well, he told me his uncle was moving to my neighborhood and he was making it seem like he was going to move in the neighborhood because he knew the name I just figured he didnt know how to work the XXXX app. He gave me this number and me XXXX he started giving me a whole spiel about him being an XXXX XXXX XXXX thats working in XXXX and hes relocating from XXXX. Thats why hes moving down here and he needs some help with his dog and he just kept saying he wants the best care for her and he was telling me very specific things that he wants done, as we were chatting for a bit about what days and what times he had told me that he had needed help running and ordering things off XXXX and he told me that he would write it under his business so that he would just send me a check and I could just order the supplies for him he proceeds to email. He proceeds to send me the check and then hes giving me a specific list like my dog needs this specific kind of shampoo. This specific dog food brand to it sounded legit. he told me that there would be a weekly pay of {$250.00}, I would go XXXX between XXXX and his company would cover this. So he sent me this check and I deposit the check on my phone using the app. Wells Fargo gives you a credit when you deposit a check. 
that the check was good because I had gotten the money for it. It told me that I had XXXX available. The other XXXX would be available some other time later. Little bit of time goes by were still chatting and then he tries to call me a bunch of times and then he starts blowing up my phone saying that he ended up finding a personal shopper that would be easier. He was thank you for your help, and then he started harassing me back for the money, I didnt want any problems. Wanted to send the money he gave me XXXX XXXX XXXX XXXX but XXXX XXXX wouldnt let me send the money so he gave me his XXXX XXXX. I sent him the amount that i had received from wells fargo. I tried to file fraud and i havent heard back nor i haventreceived any money back, i was being threatened to send back the money and I didnt know what to do. my Wells Fargo account got locked and Im down {$400.00}. I tried to contact both users XXXX XXXX XXXX i was talking to and the guy that i XXXX the money to that was the personal shopper, obviously did not work out. I have proof of EVERYTHING!! I can provide more in depth information. Do i contact law enforcement? I see old ladies ding rover all the time. This was a very well thought out scam
