What happened::
The deal was that I would buy him 4 ASIC miner Aisen A1 in 2 phases: first I buy 1 unit and if the deal goes right, I will then buy him 3 more units.
I paid for 1 Aisen A1 miner+PSU+shipment €180 in bitcoin and it was supposed that he sent me the product the next day.
The next day he said that his business partner made a mistake and that he sent me the 4 units all together. He said that the units are on it's way to my address but, he has the shipment on hold.
He said that if I want to complete the deal I would have to pay him the rest of the money.
I asked him for the slightest proof of the shipment. He refused to send me any proof, absolutely no proof at all. He wanted me to send him €400 more, no other options.
I told him that I would pay him as soon as the product arrived. he refused.
I told him to get the package back and complete the deal we made. He refused.
I asked him several times to give me any proof that he has the product or any product at all, any kind of proof of shipment. He refused.
All the deal was made on Telegram. In the end we obviously ended namecalling each other. Basically i told him: "If you have some decency fulfill the deal we made. I paid for 1 unit, you send 1 unit. If you don't want to fullfil the deal, give me the money back or whatever is left of it to this address *my-bitcoin-wallet-address*. If you're a scammer do nothing.
HE said that he will make a video of him burning my money and then proceeded to delete the hole Telegram conversation.
