Hi, I was wondering if anyone could help me... I had to send back an item to a seller and give the tracking # to paypal but can the seller say I sent the wrong item? How exactly does paypal know you sent the correct item? I'm working with an ultra shady seller who did not tell paypal yet that she received the fake back, but it the tracking info states it was already there. Does anyone know if its possible this late in the dispute resolution game to get swindled again? any help would be greatly appreciated, thanks!
