Manufacturers with Excellent customer service

Though not relevant anymore, the best customer service I’ve ever experienced, and I mean in any industry not just audio, was with Thiel Audio. Though everyone, and I do mean everyone there, was great, I have to give special mention to Shari Graham.

A small claims suit is also a good idea. Years back I bought a refrigerator but weeks passed without delivery. I demanded a refund. Radio silence from the store though I had been in contact several times a week to resolve this. Finally started a small claims case. When they were served the store called and asked me what this was all about. I told the guy- come one- don’t play games. Got a judgment which was served. 
I received a full refund plus court costs
