I just went through this ( TWICE). once with Ebay and once with Amazon.

Ebay: i bought a pair of bike shoes. The guy sent me shot gun shells. ( he has almost 500 feedback and didnt raise redflags there). I was mad. This wasnt he sent red instead of blue shoes... I messaged him and asked for proof he even had shoes. He came back claiming they were in CA. ( hes not). He refunded me my money through one paypal address ( how i paid)..Then he sends me $7 to ship his shot guns shells to a completely different paypal NOT listed and then has the nerve to tell me if i have a problem to contact PayPal. Look, buddy, youre the idiot that cant read, not me, dont get your undies in a twist. Im still waiting on shoes....

Amazon: I bought 2 bike tires. I realized theyd be the wrong size and quickly sent the seller a message. i said id return the tires un opened and could i have a refund. After getting a form answer and round about, them charging me for shipping that they advertised as free...amazon refunded me because he wont.

DONT close out disputes no matter if its paypal or ebay!! LEAVE negative feedback so the rest of us know!
