This person never paid for an item from me and told me that they wanted to cancel the transaction. I sent them a cancel transaction request after they demanded it and threatened neg feedback if I did not cancel the transaction. It was a very SUBTLE threat that I could not get Ebay to believe. So I sold the item to the next highest bidder and sent a cancel transaction request to this buyer. They denied the cancel transaction and left me VERY neg feedback after nonpayment. I was contacted by several other sellers afterward saying that they had similar issues over the years with this buyer. BEWARE!! If this person decides, they will try to ruin you. They are still sending me emails!
