OP, you have every right to be upset in this situation and I hope you get your full return!
That being said, I think using the term "SCAM" is irresponsible. A scam is an intended scheme to defraud and cheat. This also means the whole store (from management to "engineers") is in on it.
Charging the customer for damage on a new instrument return is probably their policy (probably in most places). It might be the person who handled your return is just being an a**hole. I would just call them and talk to a manager and explain you received what appeared to be a used instrument and you didn't cause the damage.
My point is these things happen: you have people saying they've used Sweetwater for years with no issues, and you have some who have had issues.
Just like in most businesses, you might end up dealing with someone who is unreasonable, or a jerk, or having a bad day and gives you a hard time. But calling it a "scam" kind of paints the whole business in a real negative light.
