Being a 1st time seller on ebay, I had the misfortune of encountering a buyer who brought a 2nd hand branded bag from me, hassled me to ship it to her despite the fact that I never actually received the money that she paid (casual buyers have their funds on hold until it is ship confirmed). In the end I shipped the item out of my own pocket, thinking I will finally be paid when she received it. Then buyer turns around and ask for a refund. The minute I approved the refund, the amount was immediately deducted from my account despite the buyer not having shipped the item back to me.

Now I am not only out of the money but without the bag too!

eBay obviously do not protect its sellers and will not be selling again ever on eBay. Meanwhile I foresee long conversation with eBay help desk on the existing case!
