Best and Worst customer service?

My vote goes for Sonic Frontiers, as Best! I was contacted within an hours, after e-mailing a question. Wery friendly and helpfull!(they can count me-in on the next purchase) Thw Worst? Linn audio! It's been over a month since i submited a Q! I am stll e-mailing the question...i am sort of amused by now!
I haven't had any bad experiences with customer service from high end product manufacturers. I have had EXCELLENT service from Audio Research, Nordost, and McCormack (steve himself!). Couldn't have been better. Definitely several cuts above the mass-market conglomerate producers. It was such a nice surprise to call and actually talk to excellent technical people.
I have to confirm the kind words about Bryston. I bought what ended up being a basket case 4B amplifier via the net. Bryston basically took care of all of the problems under warranty except for some small labor charges which they did not cover due to physical abuse. While i no longer own the amp, i can not see anyone improving on the level of customer service that i have received from them. I don't want to name the worst that i have dealt with, as i'm still battling with them and they might read this thread. Their products are mentioned here more than occasionally. Sean >
I recently bought two used Classe power amps. I have been on the phone with Classe a number of times for various reasons. Without a doubt, I have received the best service of all time. I am amazed at their consideration, honesty and generosity of time and spirit. I dealt with Robert Adam there. He is a true gentlman.
UPS is one of the all time worst companies in any category-their ability to ruin audio equipment and refusal to pay damage claims is deplorable.
