add a limited authorized user

What is a limited authorised user allowed to do or ask?What is a full accsess authorised user allowed to do or ask? What is an administrator authorised user allowed to do or ask? I'm a full accsess authorised user yet when I asked why the account says 360 protection says its part of the perks the same place Paramont perks and others are located yet there are 18 and 12 and other charges on the bill that say 360 protection. When you click on the perks it says included in plan and it states get the most out of the plan to download the app. As soon as I asked that I was ignored for 20 minutes then told only the main account holder could ask that. She asked if I needed anything else and I said yes there was a tablet added to the account from a store 2500 miles away and Aparently no identity was asked for because the person who recieved the tablet signed my name. It was even spelled wrong amd I have proof of not being anywhere near there. She again told me she needed to talk to my father. So I as a human am not even allowed to ask about identity theft that tmobil allowed. I am also concerned about no ID no account number no pin no 6 digit pass code yet a free aim card was given from the store for one of the phone numbers. Yet I'm not allowed to ask about identity theft and am being charged for the tablet still.also adding and subtracting seems to be a problem for whoever puts notes on recent activity. One of the reps argued with me as to weather Oregin had sales tax or not. Umm we live there and no tax be she insisted that she knew and I was lying. On the 14th of August I was told the bill would be fixed to the amount that it was supposed to be and that didn't happen. When I'd call the supervisor would be asking in the background how cheap I wanted the bill to be. Tell me how we have been paying $80 for the plan of 7 voice lines another line was added that was a free line and one was removed we have military disscount and auto pay and the bill is now plan is now $200 including all that we had. Its been a steady same amount for 6 months and we add a free line remove a paying line and it goes up by $120 and yet I can't ask questions now. Also 3 people are allowed to make changes according to the website so why is there 4 and who added the 4th my dad even tried to make me the administration for the account but still not allowed to ask why my name was signed and nobody on the account has ever seen that tablet.
