Paypal issue beware.

I sold a $1500 amp to someone here notified after delivery had physical damage to it looked like it was dropped. Anyhow contacted UPS to process a shipping claim. In the mean time he filed a pay pal case. Fine told him we would go through that process.  PayPal goes and gives him back his money with out tracking or evidence he sent it back! I call they said because he used some sort of mandated government payment they do not require any evidence that it was shipped back.  

What type of payment is this?

So the guy can order stuff put in a case saying it did not meet description and get money back with out returning a item? This makes no sense will never sell using pay pal again.   Just spent an hour on the phone with them.  Also I want to know what type of account this is seems like the best scam going order a whole bunch of crap say it didn't meet description and get money back and not have to return it.  I'm out $1500 paypal even charged me the fees for there great service and I don't have my product back! I don't understand how this is allowed.
