What would you do?

Recently I had a dispute with a seller. He sold me a stamp and it was incorrectly identified and was damaged. I got absolutely no response from the seller about returning it, any apologies for the damaged stamp, etc. I returned the stamp to the seller and still no response so I finally had to file a Paypal dispute. Finally after nearly two weeks, he refunded my money. Needless to say I will not be buying from that seller again, or so I thought. I purchased another stamp yesterday and it turns out it is the same seller using a different name. Obviously I have misgivings about the transaction now due to the negative experience with this seller. Any suggestions here? Can I ask to cancel the transaction? Should I pay and keep my fingers crossed that he will send it? Any advice would be helpful.|||You can retract your bid if the auction is still running. I think you have to do it in a certain time frame before the auction ends though. Otherwise try a mutual cancelation.================================================== Yes I do sell on ebay, this is my buying ID.|||I would let it play out. Maybe the seller will make good and send out a perfectly good stamp. Wait and see|||You are obligated to pay for your bid on the latest auction. One transaction has nothing to do with the other, as far as Ebay is concerned, unless the other first seller user ID is NARU (not a registered user). Pay for the item and depending on what happens, act accordingly.|||You can request a Mutual Cancellation, which the seller is probably willing to give you since you have been involved in an earlier dispute. An MC ends a transaction with no fallout for either party, but it must be started by the seller. Ask politely but do not be afraid to refer to your earlier unhappy transaction. If he goes for it, respond promptly and agree. You will then both be free of the transaction In a handshake business like philately, trust, once lost, is hard to regain. If this were a DVD my advice might be different.|||||||||"I would go as far as to say that if you do neg them again, the seller may file a Unwelcomed Bidder against you and win. " Seller obviously did not block the OP on their "other user ID" and the OP had no idea, they were the same seller until post auction, so the "unwelcome bidder report " will not fly.|||
