I would maintain that good customer service makes zero difference whether you are buying a partscaster from a local 'unknown' for $500 with stuff scrounged from ebay and garage sales, or $5000. I think the fact that he paid so much for a bass that is apparently unplayable and with way too many cosmetic flaws for the price and is being treated like poo is the core issue that's got folks' dander up.
+1... I would hope so too.
