*********** and Incapable customer service

I recently moved house. I contacted DStv to have my package changed from Premium via Decoder to Premium via Stream. I confirmed my needs with the agent and that the package was right and that we had done everything we needed to. Today is the billing date on my account - no debit order ran, because the services were disconnected by the agent. I have since been on the line with 2 other call agents and 1 further WhatsApp agent. They have not been able to assist me and each interaction was ended before completion - I am beginning to think deliberately. I have the screenshot from the WhatsApp chat to show the agent going quiet, me following up, her promising that she is checking my account and then the chat being disconnected because I didn't reply to a response that never came.
