Telkom Mobile call center Agent and manager

I would like my distasteful experience with a telkom service agent (Nontobeko Ngubane) who is very rude and fails to listen to the customer always jumps in when you trying to understand the situation. I then asked to speak to the manager (Lungi Cele) but the manager herself sent the agent to tell me they can’t help rather I wait. I find very disrespectful that you try speak to a senior to get more clarity as they have more knowledge in this case I feel the manager is very childish.
