Well, I finally got a response. Here is what they said:
"Chris,
we are a small family owned business - that is what we wish to be. we always have and always will do our best to handle service matters as quickly as possible.
Although our website does provide some level of expectation for an airbrush to be serviced - our service is provided on a best of our abilities basis. Sometimes a service matter can be turned around in two days - sometimes two weeks - in some unusual circumstances it may take two months. (But we'd usually come up with an alternative remedy in a two month situation). In any case, we do our best to service and return sent in airbrushes as quickly as possible.
In answer to your question - we have one service technician - just as we have had for 50 years. He works Tuesday through Friday. Service technician is not his only job function.
Our only standard for service acceptability is to provide the service to the best of our ability as quickly as possible - always striving for customer satisfaction in the performance of their Badger Air-Brush Co. product. Our reputation of conscientious service and product support is unmatched in the airbrush industry.
I apologize that you ended up in voice mail - I was the person who answered the phone when you called. I was the reason you ended up in voice mail as I did not know the service tech was on another call at the time you called.
I believe your airbrush service was completed last week, and shipped back to you on Friday."
No mention of the request I sent in along with my brush that I needed them to include the fine needle upgrade kit and that I needed them to contact me when my brush arrived there for service. Their service may be ok, but their communication skills are terrible.
I've always regarded Badger as one of the "Big Ones" along with Iwata, Paasche, Grex, etc. I guess I expected that Badger was a much larger company given the popularity and international reach of their product. I guess this isn't true. Considering they are operating the same way they did 50 years ago, with a single service technician, I'm amazed they've survived this long.
They have a Twitter, but it's been quiet for a couple years as far as I could tell. Their last Facebook post was back in January.
