After I had given him his payment through the Zelle App he asked for my name and address that was on a Tuesday is now the next Tuesday so it has been seven days exactly. I haven’t been able to contact him through the phone number that I use on the payment app and I wasn’t able to contact him through the other phone number that he had I looked up his name Martavius crump and he had one person as a friend on Facebook. Is there any type of security for the buyer if the seller is scamming? It would be highly appreciated if I would get a phone call back regarding this issue of money being stolen.
