>>Stop Using PayPal!<<
Okay, PayPal is easy and convenient in some cases as it's just give someone your email > receive money, but not always. I recently had an experience where I sold something online, he PP'd me the money and I thought I was good. The SOB charge-backed and I was straight fucked. xD. In this case the only way to resolve it is if they close the case and sometimes that's damn near impossible.
**This is off topic but needs light to be shed on it. PayPal also holds your currency when you deposit it to get interest on it. How do you think they would make their money? Being honest, providing good services? No. They will just hold your money before it gets put into your bank. Such a scummy thing to do, but they do it.
So, from now on, I would try to use Bitcoin more than PayPal. Be careful!
