somewhat depends on who you get on the phone call
Like my title says...it can depend on who you get on the phone. It can be hit or miss.
My interactions have been generally good with good results but once I got a man on the phone who was clearly "hassled" or hadn't got his coffee yet, or the boss wanted a report or something, etc. et. al. ad infinitum. He was very brisk and short tempered...blew off my request for a owners manual on a current series M&P 2.0 Compact.
A call again same day but hours later I got another agent who gladly took my address, and sent one right out.
Other requests for information over the years have been handled very satisfactorily in my opinion. Before I found this Forum I used to ask really dumb questions, like "what accessories would have been packed at the factory with my 1971 Model 36?" I know they probably didn't have a digital answer immediately in front of them on a computer, but I was never on hold for more than a few minutes and I'd get an answer!
Like others have said already, I think it can also depend on how you act on the phone too...come across as belligerent and you may get the same in return..do they "owe" you an answer?
Just my two cents.
