Buyer needs to post up pics or video of the cue making the sound or something. Both buyer/seller are barely active on this site so I can't see how anyone can side with the buyer or seller.Either way, hopefully things get sorted out.
There's no sides to this. The buyer doesn't like what he received. He returns the cue, he gets his money back. Nobody is right or wrong, no decisions to be made. If you sell sight unseen, you have to guarantee satisfaction. If the buyer is "too picky" and "should have been satisfied" what's the big deal? Just take the cue back and sell it to someone else. If its a fair deal that should be no problem.
