Old ticked unattended - I can't wait no more - going public

It has been 2 months since I have logged a call with Rain after purchasing a R999 5G package from them. I called to inform then that as much as this router indicated that it is picking up the signal, it is not strong nor stable. I have now called 3 times and I am told the call will be escalated to a technical department. For the first time when I spoke to a call center agent this morning I received a call back from a person whom I was told is senior at the call center. She promised to call me back urgently after explaining the one thing I have been explaining. I have done all kinds of troubleshooting and interface logging as guided. Those will not help and have not. I did my groundwork and was able to reach a technician who was helping my colleague two days ago in another town. When she allowed me to speak with the technician, the technician indicated the solutions to the problem and it has nothing to do with troubleshooting. Let me be clear on this, every month Rain is debating R999 from my hard earned money and the purpose has not been served. I received a call as I was typing this. A person from the technical department tells me she can not send a technician today because of a schedule. Schedules are developed by people and can be altered by people. She says a technician cannot come today and when I tell her of a willing technician she reverts to telling me about a schedule. She then tells me that she doesn't allocate technicians, a supervisor does. When I request to speak to a supervisor she does not seem keen to enable me. I have the names of people I spoke to recently, I just don't want to infringe their rights as much as I have been truly exploited by Rain. There is this mention of floors which cannot be accessed by the employees of the same company who are supposed to work together to ensure customers are assisted and have the service they are paying for. I cannot wait anymore and I need the money paid for the 2 months used as advance payment from the day this is sorted. If I do not get a proper assistance till 14:00, I am moving on to public media platforms and will state the names. I have the ticket number for verification.
