No Mobile Service

I have been trying to get hold of my Financial Advisor. I managed to find her office number after 3 weeks. Unfortuanately her service was suspended by Autopage. An outstanding account of R5,000 outstanding. According to her she has paid all her accounts every month. She made an enquiry last month and found out that 4mb of data is owened to her, because she did not use her 1mb monthly. She uses her phone for business purposes only. She is a single parent who works on a commission basis. If she do not have a mobile available she cannot make ends meet. Please assist, because she is becoming desperate and after several attempt to sort out this problem she is still without the use of her mobile phone, which is paid for every month
