Bad call service

I have a contacted DSTV inquiring about my balance and as we having this conversation with the agent, it seems like he does not know what we are talking about (No product knowledge). I ask him to transfer me but he insists that he is right until finally he struggles with the answers. He moves to telling me that he is just a worker at DSTV and does not own the company. It becomes a joke with his fellow colleagues which shocks me. I ended the call without the issues being solved because the agent does not know about his products and rude.
