Poor customer service

I paid on the 9th of December, I sent through proof of payment on the 9th and I received an email with the reference number. My service was disconnnected, when I called the agent told me he had found my proof of payment and service reconnected. But 3 days later was disconnected again. I have been having the same problem every month. I speak different people who escalate and reconnect only to be disconnected again. I called yesteday evening and the agent told me she will escalte the matter to payment department and my matter will be solved, she promised to call me back but no one called me. I called again this morning and another agent promised to ask Masel Pikhambo which they claim is the manager to call me since 12pm till now. I called again with my airtime, I have been on hold for 15 minutes now, still waiting for assistance. I am not happy at all, this is how you treat your customers, we pay for our DSTV every month and we still must have airtime to call. This is not acceptable
