  1. I am at this moment on hold for a supervisor with t-mobile and have been being charged for over a year for a “virtual line” that I did not authorize. I recently saw this on my bill and when I called no help. I don’t understand how this company stays in business doing this to customers. $30 a month for a virtual line that has never been activated. What does virtual line even mean. This is in need of a class action law suit. Check your accounts and contact me reference charges that are unauthorized on your phone bill. I am in contact with a law firm to assist in theis matter.
