Got a SATA cable in the mail today, which isn't exactly what I ordered. Somehow there must have been a mixup in shipping. The phone number he gave me didn't seem to work, but I was able to find the right one and I gave him a call at home. He was very apologetic for the mistake, and agreed to fix it within 24 hours. I remain suspicious, but I will follow up in this for anyone else interested.
I don't really know anything about the circumstances, but being apologetic and making (empty) promises is a very common scammer behavior. Watch out.
On the flip side, what's an honest trader supposed to do? If I were selling thousands of dollars of GPUs, and there was a screw up, I would be apologetic and trying to fix the situation.
He claimed he must have accidentally sent them to Leezyist. I find it hard to believe that he could have done that, but who knows. He actually did have the cards in his possession as he sent me a photo of them with his name and the date on them. The mistake is hard to believe as the DHL documents he sent me showed the weight and value as 10x the numbers as were listed on the actual documents I received.
His story does seem to check out though. The person he was fundraising for to help her sister actually does exist, though her Facebook page doesn't indicate if she's left yet. Sylkyx does also live with someone with the same last name as her as well, which was how I was able to track down his information. Who knows, maybe he was desperate to help.
Really, I'm too pathologically honest. I was extremely suspicious of this, and other members counseled me to just wait for the package to arrive before sending anything. In the end I did because I had agreed that I would send half upon confirmation of the package being sent, and that was fulfilled. Still, we'll see what happens tomorrow, I'm actually hopeful that he'll return what I paid. I may not be in England, but I do know a lot about him. He got a relatively small sum of coins, and for most people it wouldn't be worth me contacting his foster sister, his parents, former employers, the local police and his profs to explain the situation to them. It might not do anything, but if I were a prof and I received reasonably solid proof that a student of mine was committing fraud on the internet I might not do anything about it, but I would definitely look twice for academic dishonesty in the future.
