Thank You BegottenPoet228 and all. I guess people really read my comments. I think each of us has had “something go bad” and cannot get good CS. With AMZN and Costco, I never have an issue. I was impressed with Linksys and their TS, because that fellow hung in there and we got it. So hats off to them as well.
Another company with Excellent Customer Service is Laminar (X-Plane). I have routinely contacted them and received a reply on my query the same or next business day. One time Austin sent me a reply directly, and that my friends is the head of the outfit. So the difference between excellent CS and poor CS can be measured.
