Old woman was paying, but not using an account

<p>Since about March 2015,my mom struggled with her cellphone. She stopped using so long ago, I don't know the correct date. I got Power of Attorney over her. As I tried this week to cancel the contract, I was send to 6 different departments and then got cut off. The 1 lady told me that the account must be paid up first before canceling. I cannot find the correct amount amongst her paperwork and now one seems to be able to help me with that. As I got madder and madder of their incompetency, I realized I will be paying for nothing as the phone was never used. My number is ********** 827. Her number is ********** 652. HMH Esterhuysen. Please can someone just contact me? My mom has dimensia and I have a doctor's letter on that as well</p>
