If you paid with paypal, it can take anywhere from 15-30 days depending on the situation. If the person just won't respond to you and wont refund then you file the complaint. Paypal sends them an e-mail with options to settle or contest. If they do not respond to paypal, it is settled there in your favor. The person I believe has 14 days to respond. If they contest the charge, it will take up to 30 days.
