I attempted to complain about fake warehouse address a few months ago and the experience was painfully onerous. In the end, ebay said that they will check my complaint, without any follow up. Nothing was mentioned on how to handle these products since they are delivered a month later and the buyer (me) already bought a replacement. I attempted to get a refund, but the Chinese seller always say:
"Sorry ,my friend . We can give you a discount will that be ok?"
(Notice the misplacement of punctuations. Chinese sellers often misplace them. That's an important clue to tell a product has a fake warehouse address, but that turns ebay experience into detective work.)
These sellers have limitless energy to reply to your requests in kind words and no matter how you scold them they will neither admit nor deny their wrongdoings and never gets angry.
In the end, it's not possible to ship them back because it was labelled with an address in China. The best option for the buyer is to accept a discount and call it off.
I know the only true answer to this question: use Amazone instead. If ebay could have improved it they would have, since studies showed that delivery time is a key factor for e-commerce and ebay must know it. But I somehow feel I need to do something about another package that arrived too late to be useful. Should I just keep it and leave negative comments? How much harm can I do anyway?
P.S. I am Chinese myself and this annoys me like hell.
Don't order random crap from unverified or unpopular sellers then? Read their reviews and ratings. eBay and Chinese/HK dropshippers thrive on each other, you and I aren't going to change that dynamic.
