Literally everything else.
There's no clear pay scale or raise structure, and HR is not forthcoming with this information, either. The commission structure makes little to no sense, changing mid-month in a point based system, random spiffs for anywhere from a day or two to a few months. It's so confusing that there's regular trainings and quizzes on how the structure works to make sure employees come even close to understanding it. The median monthly earnings in commission are only earned by 38% of employees, not the average or majority.
The training is almost useless, and focuses on convincing you you can make good money rather than teaching you anything. They push ethics and "honest sales" in preaching, but not in practice; and punish you for "underperforming" if you don't slam account with extras, lie to customers, or commit blatant fraud. They actively discourage you from helping in any capacity if it doesn't create a sale of some kind, and push extra fees onto customers for something as simple as paying your bill in person.
Regional supervision isn't required to follow the same standards as company policies, and there is very little hierarchy accountability. They expect you to answer a call at a drop of a hat even off the clock, but will actively ignore you or hang up if you need something when they're off the clock, even salaried. On top of that, upper management and the C-Suite is rife with nepotism, and even Verizon thinks they pay their employees too little.
Not a great look.
