Hey guys,

Lately I've got a negative feedback from a suspicious buyer. The buyer contacted me claiming that the item didn't work, but no proof at all, no photos, no nothing, just statement. Then I proactively communicated with him and provided troubleshooting instruction and told him that if the item still has issue, return for refund or replacement. 

Then the buyer left me a negative feedback immediately after I sent him the resolution message. Although eBay's policy stated clearly that leaving negative feedback for requesting refund before the buyer send the item back to the seller is not allowed, and is considered feedback extortion, eBay favored the buyer and refused to remove the feedback.

I think eBay is not fair for sellers at all, when seller has done everything fulfilled element on the transaction, why we still need to be the one who is bullied and accused? 

Do you guys have any similar experience or maybe suggestions on this?
