buying from sellers who state no refunds {833440 seller

i bought from a seller 833440 who hid behind the statement no refund look at picture and you should not have to return. with that i purchase a part and received a wrong part. item stated 69 firebird brake booster and i get a 79 brake booster. when stated the fact to seller i was told ebay can do nothing about it. and i am stuck with the part. started a dispute with angry seller. then i was getting the part to be returned. seller stated i need to return part and i pay shipping both ways and refund of ebay action listings. because i bought the wrong part as he stated so i should pay for everything . all in all i was very shocked at his attitude. he had a very good feedback. just be careful crafty sells tactics are easy to overlook when buying on ebay and as i learned you could and probably will be stuck with what you get.
