Welcome to Intuit Support. Based on other posts here, your experience is somewhat typical.

Gone are the days where you'd call Intuit and they'd just pick up the phone and help you. Years ago the complaints were more like, "the hold times are too long" and "I had to talk to three people in a row". 

Now they're more like yours: "I can't get any help. Reps don't seem to know how to help me. I'm promised callbacks that never happen. And worse, when I call back to escalate, I'm "mysteriously" disconnected. Over and over."
