eBay fraud is more the rule than the exception
I purchased a small computer part on 20 September. With shipping, the amount was about US$13. I paid by bank money order and the seller marked it "paid" on 22 September.
I have not received the item. The seller claims it was "shipped and returned." eBay has not addressed the dispute which I opened on 22 October.
If I have not received satisfaction by 22 November, I shall file a claim against the money order (with the bank) for fraud, and report eBay to the State Attorney General for conspiracy to commit postal fraud. they can out the seller, or not; I don't care.
