No, it's called "consumer protection". Getting what you paid for isn't just up to the whims of the seller, where he's free to just decide to alter the deal he made with you at his own convenience merely as he sees fit, without your consultation or permission.
In that sense, of course, trickyric is certainly entitled to get the bass in the condition it was represented to him by the seller in exchange for the purchase price. Sure, each side has to be able to negotiate and compromise in case of a problem, but you can't have one side or the other changing the terms of the deal willy-nilly and/or refusing to honor their side of the purchase agreement.
So like I mentioned in my previous comment, it's good to be patient and go through whatever process the seller might need you to, and allow him to attempt to resolve the problem.
But OTOH, if the seller really does try to renig on the deal or otherwise can't or won't honor his obligation, trickyric, like anyone else, is well within his rights to pursue compensation one way or the other.
Under no circumstances does he have to accept any less than what was presented to him as what he bought with his money.....
