demon.....I doubt that you're dealing with a Samsung owned/operated repair facility. Yes, you will call Samsung and they will connect you to a local/authorized repair facility. The repair facility which can be John's Auto repair or George's used appliances is the one you're having difficulty with, not Samsung. Ask Samsung to select another repair facility.
It's like saying all Chevrolet's are junk because you had a bad experience with a dealership.
Even if the Samsungs have a 1%-3% problem rate, they're still head and shoulders above a Norcold. I can buy three Samsungs for the price of a Norcold.
