I think customer service, in general wherever it's encountered, has declined in civility since the pandemic.
Add to that there was a slight uptick in firearm & ammunition sales as another side effect, but also a decrease in supply, - I'm not surprised gun stores have been unresponsive. Particularly if specialty gunsmithing is required.
I have had good service from Brownell's, VPI, Cabela's, Track of the Wolf, Dixie Gun Works . . . . most of the big online presence.
The worst experience was having a bolt modified by a cantankerous gentleman running a one-man shop and backlogged. But, eventually it turned out OK.
Does not excuse rude behavior, nor failing to live up to what's advertised.
Maybe a behind the scene bidding war?
