No way would I have offered anything in the same breath as feedback.   If the buyer had a legitimate complaint I would have refunded without asking them to revise the feedback.   If you had tried to bribe me into changing feedback I would have absolutely refused.   Your neut would not have been so noticeable if you hadn't responded to it, I would have left well alone.

What is wrong with the follow up feedback I left? I was courteous didn't attack them? In addition out of some 27 feedback left by buyer 6 are either neutral or negative. A broken case is such a trivial matter. If the buyer was legit they would have accepted a replacement case which I would have sent via express and ahe would have had it the next day. By note responding would have been worst - I stated facts and most of all buyers can see that I care about issues that come up.
