I have had so many problems with Maritz...every one my responsibility, too. Like I'd go do a route of gas stations, come home, and the internet would be out. Or my PC just wouldn't work, and I'd have to take it in to get it worked on before I could submit my reports Like I was hexed when it came to Maritz (had the exact same problem with The Source, too; but not with dozens of other companies, LOL). I finally got to where I just wouldn't ask them for shops. Because of my record with them (although, in the end, I don't think there was ever a flake or cancellation, just dreaded the reports because something ALWAYS went wrong). I never reached self-assign status (also with The Source!).
But they never cut me off from any of their shops, and when I do shops for them, they are always nicely bonused.
I can't imagine what egregious behavior it would take to get blocked, LOL.
