I think you are correct. My experience with phone techs or any tech for that matter, is that when I get someone who knows what they are doing and how to assist, then I'm indeed a lucky fellow. But, when I get a tech who is largely inexperienced, at least with my problem, they "punt" until perhaps they might just luck onto a solution, however temporary, or fail miserably in assisting me, making a bad situation even worse.
I had the same experience when I first had the credit card denied problem. Eventually, I was turned over to someone who apparently knew exactly how to reset my account, did so, and it's been no problem since. Took two weeks, but constant pushing from my end finally got me to an informed tech. I think the original tech just got tired of my constant badgering! LOL I do, btw, make a point of sending a review of my experience along with a log of the conversation -- good or bad. Even if they don't survey me for one.
