I just learned today that someone filed a dispute on my old paypal about 7 days ago, which is still linked to my current ebay. I was about a stick of ram I sent him about 2 weeks ago. Once I located the tracking number, I found that the address match, and even called ebay and paypal (paypal just told me to contact ebay though.) for some confimation, so once I entered in the tracking number in the paypal dispute, I went to message the guy on ebay. But here is the thing: accounts gone, unregistered in that week span, what's even more weird is that I was also trying to contact him regarding the paypal payment while I was shipping it, as I need to fix a email on it, he never responded to the 3 messages I've sent him. His paypal email doesn't even look real, and it doesn't even match his account name, which I assumed to be a computer memory company, each email looks like a company name and have the year at the end of it. So, I'm confused beyond this point as to what I should do, I've tried sending email to the paypal email as well, but he hasn't responded, so I can't seem to contact the buyer, and I'm still wondering how a case is opened for a unregistered ebay account.
