Billing number:Ba***

I am so dissatisfied with the service levels MTN South Africa gives us. My brother took a contract 2019 and the contract lapses this year August. He has been trying to make contact so he can cancel it but they giving him a run around. It is very frustrating. I trust that we will get response as soon as possible because should there be any incurring charges we will have no choice but to take this up with the ombudsman. Because this will impact his score negatively. Your assistance will be highly appreciated.
