e bay and paypal rip off

I bought an amp from a clown called boandsav,the amp was not the described one.he wrote back its my fault (really) and would not refund.I contacted paypal who agreed it was not the amp I bought and was told I should ship back at my cost to recieve refund.so I'm $24 out of pocket.e bay and paypal are a joke and certainly don't look after their members.
