JMOfartO:
I'm old, so maybe I think a bit differently (slower for sure) than you young folks, but in my experience I have learned that if I'm dealing with a particular person or business, and everything is "hunky-dory" (whatever that means) I try and give them all the business I can, and recommend them to others.
If the circumstances change and I become dissatisfied with the service, products, whatever, I start searching around for another person, business offering the same good services as the first had originally.
For example, the local ffl transfer dealer here in my small part of the U.S. (S.E. Ga) charges $25.00 to accept a transfer in, and $10.00 to transfer a firearm "out". (I do the packaging).
We have been doing this so long now that we have become personal friends, and anytime I have an interest in a new firearm I go to him first and give him the opportunity to find me whatever it is at a reasonable price.
I don't mind paying him more (reasonably more) than I could get one online, or elsewhere, because he's a small businessman, and I try to shop locally when I can.
When I want something he cannot get (surplus P7's/ old lever action Marlin rimfires, etc.) I find them online, buy them and ship them thru him, getting him at least a small piece of the "pie"..
It's a nice arrangement.
Having said that If he quit providing me a service at a reasonable fee I'd look elsewhere for another gun dealer who will..
Just business.
I suggest you start shopping for another ffl transfer dealer, today, and asap quit doing business with the one giving you the run-around.
But, it's never a good idea to "burn your bridges", as you never know when or if you might need the services of this particular person, or business in the future..
Hopefully never, but at almost 69 years old I've learned to "never say never"..
Best Wishes,
Jesse
