VODACOM BULLY AND MISUSE ELDERLY PEOPLE AND DO NOT REPLY

Dear Vodacom, I have placed a review on Friday - no response - Again, My father is 70 years old and a very good paying client I do believe. Me and my sister is trying to sort this out because we are worried as he have heart problems. My brother have a contract on his name........How did this even got approved? have you got a signiature from my father?,.........and my brother is not such a good payer, Vodacom does not get back to us on what to do to get this contract of my brother on my fathers name stopped. Why do we have to beg to get this sorted out? This contract is getting billed every month, without even being used? Can somebody please help? Do we have to go to the ombudsman?
