Product: Money transfer, virtual currency, or money service

On XXXX I responded to an Offer Up listing for a second-hand XXXX XXXX  called XXXX XXXX XXXX It came with a XXXX XXXX and it was listed at {$1700.00}. That is a pretty good price for that combination. Me thinking that I could purchase it and resell it on XXXX, I responded to the advert. The gentleman from the listing was named XXXX and he was located in XXXX XXXX, Utah. He responded about 45 min after I enquired about the product. He told me that he could send me photos on my phone if I was interested. I promptly agreed, and he sent me photos from his phone number ( XXXX ) XXXX. The pictures came in and the XXXX looked to be in good shape. I was eager to purchase the unit. He said that if I was interested in doing the transaction via XXXX. I told him that, to avoid anything weird, I would much rather wait till he got to XXXX and either gave me a call or texted me when he is shipping it and I'd get the tracking number off of him then and then I would make the transfer via XXXX. He agreed and we left it at that till XXXX. He then proceeded to let me know that he already had shipped the unit out earlier during the day due to him having a bit of a break at work and that he had the tracking label. He then proceeded to notify me that he would feel safer if the tracking number was blurred out until I sent the XXXX payment. He sent me a photo of a Tracking label and a XXXX receipt that both had tracking labels blurred. Both the receipt and the Tracking label had XXXX on them and my name and address and all the information detailed, as I had already given my information to him so that he could give me an estimate for shipping from Utah. Not thinking that this was a weird maneuver, I promptly agreed and asked him for his XXXX information. He gave me an email address. XXXX. He had notified me that I was to send the XXXX to that email address because it was a business name. Before sending it to that address, I noticed that it said XXXX XXXX. I didn't pay any attention to it as I was eager to get the purchase. I sent him a total of {$1700.00} ( XXXX TRANSACTION NUMBER : XXXX ). The price of the XXXX plus shipping plus gas to get to the XXXX and drop off the unit. He then responded 30 min later saying that he was driving and that nothing came through yet and that it seems that we need to give it some minutes to process. And then he asked me what it says on my end. On my end, it said that the money had been delivered and I sent him a cropped screenshot of my bank ( JP Morgan Chase ) confirming that the money had been delivered. He then proceeded to send me a screenshot of his bank app. It said that the {$1700.00} payment had failed and that it was being refunded in 3 business days. That it was being sent back to me. I then thought that was weird, as I have done {$2000.00} dollar transfer before via XXXX and it worked out great. I proceeded to Tell him that I would try it again. But that I had a daily limit of {$2000.00} dollars on my XXXX. He said, if I could try to send it to his wife. Her name is XXXX XXXX ( XXXX ). I agreed that I would try to send it over to her. When sending money to her XXXX account, I noticed that I was only able to send a Max daily limit to that account of {$500.00} dollars. I notified him of this issue and told him that I would send the {$500.00} dollars today and tomorrow I would send the remaining balance. He agreed, as the XXXX of XXXX was a Holiday. The {$500.00} dollars ( XXXX Transaction Number : XXXX ) went through from my bank and I still owed the remaining balance of XXXX. ( {$500.00} + {$1200.00} = {$1700.00} the total of the XXXX and XXXX ). The following day, I sent him two payments of {$620.00} ( 1 ) ( XXXX transaction number : XXXX ) ( 2 ) ( XXXX transaction number : XXXX ). I had thought that maybe his bank were rejecting my XXXX due to a large transaction all at once. So I had told him that I would split up {$1200.00} into two transactions and he agreed. My bank did flag this transaction and called me. But not thinking that there was a scam commencing, I spoke to the gentleman, and I told the bank that it was a legitimate transaction. Both of my transactions went through on my end, but he again sent me screenshots from his mobile app that showed rejected and sending back to my bank in 3 business days. He then proceeded to notify me that he had to put the package on hold on the XXXX app until the matter got resolved. He proceeded to share with me a screenshot. I told him that I understood and that the only other option was for me to send him a XXXX transfer of the remaining {$1200.00}. He was initially reluctant to the idea. According to him, he wasnt able to get access back to his account because it had been a while since he used it. An hour later, I received a text from him stating that, his work colleague had an account and that if I was comfortable, I could send her the {$1200.00}. I was annoyed and just wanted to get this transaction over with, so I promptly agreed. I sent {$1200.00} ( {$1200.00} plus XXXX fees ) ( transaction ID : XXXX ) to his colleague ( XXXX XXXX ) via XXXX friend. I used XXXX XXXX to make the transaction. 30 minutes later, He notified me that the payment had gone through and he had removed the hold on the package from XXXX and it should be delivered on XXXX The package never came and it never has. I was ghosted by XXXX. I promptly contacted Chase on XXXX and they told me that they were going to try to retrieve that money and to wait for 3-5 Business days. I never got word back from Chase until XXXX when they said that their pursuits of retrieval were unsuccessful and that I needed to file a report via XXXX. So I promptly filed multiple reports for all of the transactions with XXXX on XXXX On XXXX I recieved a response from XXXX saying they can not help me and to contact my financial institute. I am aware that EFTA Regulation E protects me in these matters, but anything to help me would be great. Thank you!
