Absolutely apalled

I tried out the new chat function on the Telkom website and was chatting to an agent named Daniel Mathee. I needed to discuss my bill as my service was suspended. At exactly 17:00, he ended the chat with me while I still required his help. Today, as I called him out on it, he then ended the chat again. This is exceptionally poor service from telkom. I demand some sort of action. Are customers just supposed to be ok with this? I've taken screenshots of the chat and will take this further.
