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!
Thiel is excellent. I blew a tweeter in my 3.6s that was absolutely my fault. They replaced it free. Worst is Goldmund. They can only be contacted by e-mail, and it takes about two to three weeksfor them to respond. I had a problem with my SRMs. A distributor sent it back for me, which saved me hundreds in overseas shipping, but it took over three months to get them back. I would hesitate to buy anything foreign made without good US representation again. I also had a pronblem with KR amps. It cost me about a Grand for shipping to and from. At least they answer their e-mail promptly.
Best: Sonic Frontiers. Excellant, prompt service by e-mail. Very happy with service.
Cardas has great customer service. I emailed George Cardas when I had a problem....the response to my email was received within hours. To make a long story short, he replaced my cables with ones that were 1/2 meter longer, at no charge. . His Neutral Reference cables are great-sounding ! VPI is also very good for customer service. As well, I like their philosophy that just about everything they make is upgradeable as funds become available.
