Uber expensive repair at United Radio

I've dealt with United for several years,  mainly with Consumer level receivers, amplifiers, etc.  I've also been in the AV business most of my life and have owned all kinds of the good stuff as well.  Being in the business and having to deal with Customer Support all these years, CS has really gone down the tubes with a lot of the Vendors, esp. this past year. You can't blame Covid for poor CS, in most cases, I believe.  Business that care about there Customers will find a way to make things work, or at least give it there best shot.  So where am I going w/ all of this?  I've had 3 high end receivers that were sent into United this past year on separate occasions.  I have not experienced the level of quality that they provided by any service center that I can ever remember.  I filled out their forms, sent the pieces in, got an email response when they were received at United, plus received a status call on when it was shipped, and a follow up after I received it. The repairs took less time than they had estimated as well.  Needless to say, I'm impressed with there service, esp. with all that is going on. It made me want to do better at what I do, too.   I can also tell you that a lot of the manufactures aren't taking in equipment for repair because of the parts shortage that's out there.  A friend of mine works in a very High-End audio store, and when you walk into one of the rooms there are stacks of products sitting there waiting to get an RMA so they can get it fixed or replaced.  There are some products out there that have been at the Manufacture for over a year, waiting for parts.  The largest DAC chip manufacturer burned down in Japan last year and it's affected AV, Automobiles, etc.   Anyway, it's ugly out there in the electronics world.   That's my soapbox!
