    What a shame! Man. You complained without any evidence that I sent the wrong product to your order. And you opened an eBay case, eBay said what you complained about is B.S. Then you leave this comment on the other 2 orders. This order, you told me, ordered the wrong product after I shipped it out, and I accept your return request. refund has been issued even though the returned product has not yet been received.

    What a horrible, selfish guy you are! You complained without any evidence that I sent the wrong product to your order. And you opened an eBay case, eBay said what you complained about is B.S. Then you leave this joking comment on the other 2 orders.
