CELL C - NO SUPPORT - NO SOLUTION -

We have been trying to sort out my father in laws account since April. He keeps getting threats regarding non-payment, yet funds have been drawn from the same account for over 20 years now they have just stopped taking payments. Zero response from the support lines and emails. One response from facebook where they contacted him and promised resolution and this month he was cut off again. He is 83 years old and totally reliant on his phone. Why can this not be fixed???? It's a simple problem. Where is the simple solution? Time to change providers. Cell C shops are also unable to provide a solution. How to get out of this contract???
