Vodacom treating me like trash

I called in to vodacom to make a query if they have received my payment. Once confirmation was received I asked to be transferred to the cancellations department. A consultant named Denver answer the call. Initially his system was slow I was patient with that. As the call continued Denver wanted to convince me to keep number cos my brother is using it . I asked him nicely to cancel. Spoke to me like I'm a fool who doesn't understand. I continued to say pls cancel. He kept on saying I'm not understand even thou I told him I understand and he should cancel. I think he wanted to bully me , corner me into doing what he wants.Vodocom consultant agent Denver made me feel stupid or nt intelligence mayb cos of age ,agenda or race ...?I'd like to know why he undermines customers ?? On top of that while I was talking he hung up on me. How disrespectful. I was left not knowing if my request went through or not.

No manners at all. I'm not sure whether this is the way they are encouraged to speak to people. Or whether there is no structure or order on professionalism or disciplinary.

So what happens after he treats me and others that never reported this...? I'm not happy. I'm dissatisfied I'm disappointed
