Not sure I fully understand what you're saying. What does one have to do with the other?If a company replaced my neck twice on a guitar I'd think the customer service was doing a bang up job. That's three necks! Maybe the SS isn't for you is the real solution.
Further, it happens that mass produced necks come out of the shop with faults, this is fully understandable. When you're replacing one however wouldn't you make sure the replacement leaves the factory flawless?
