Okay...I recieved a $500 payment on paypal from a guy for a programming service i provided him. all seemed good... then i find out today that the guy had some unsavory business practices and paid me with money that got charged back on his account. so now the money that i already withdrew from my account is held, and im responsible to put $500 back in! wtf is up with that? why am i being held responsible for his idiocy?
