TMobile TMobile Family Allowances Rip Off!!!!!!! Portland , Oregon

I set up my daughters line to have family allowances so that I could monitor her use and/or restrict certain numbers and times that she could talk, text, etc.... For nearly a year now I have not been able to access the services to perform ANY of these functions.  In addition to this I have to call TMobile EVERY month after my billing is generated and sit on the phone for 20 minutes or more getting them to reverese these charges EVERY month!  On top of it I also ask them to cancel the Family Allowance plan EVERY month and their answer for the last 3 months is that their system won't allow them to cancel the service!  They are going to put in a "ticket" and this will supposedly resolve the issue although this "ticket" has done nothing for the last 3 months either!  I have been a TMobile customer for over 8 years but have to say that their services are absolutely horrible these days!
