Guarantee I can tell you what happened here.

OP set up a circle ring payment system. He bought $500 paypal my cash cards for $275-$325 in BTC and then bought BTC using those funds. When paypal saw his loading pattern they immediately froze his account. Paypal often will reverse payments made from funds of paypal my cash if they suspect something.

When I was loading PPMC they froze my account and put all payments made using that last $500 on hold and reversed them. Even though I said it's their money.

Have fun with that one OP you obviously don't have a business account with em so you're probably fucked.

It's likely the OP never tried charging back as he claims and that paypal reversed the payments on their own. But who knows really.
