This company is part of what is wrong with this country!!!

What pathetic service and the so called "whats-app help line", please help me to hang myself. Received my sim for my fixed line LTE last week Friday, 20/09/2019. I put it in my modem on Monday 23/09/2019 and make all changes as instructed and I have no service. I send a message on Whats app, an agent gets back to me two hours later and says they will send through an activation request. It will take 24 hours to activate. I give them the benefit of the doubt and take the public holiday into consideration. I get an email for a bill from 23/09 to 30/9 services on 25/09/2019 and I pay it. I send another Whatsapp, I am asked to send through my POP and my services will be activated within 24 hours....but wait I was told that on the 23/09/2019. The 26/09/2019, I try and connect again, what an epic fail. It does not work. I make a call to the Supersonic office and tell them to cancel everything and refund me for the services I have paid for but have not received. The accounts lady is helpful and tells me it will be done by next week Wednesday. A help desk agent on Whats app starts harassing me to fix the problem and says they understand my frustration but let us try and fix the problem. Hell no! The service is pathetic. The help desk agent then says I need to give a month notice to cancel. Little does this agent know that I know my rights as per CPA. I will return their sim card and will make sure everyone I know learns of the bad service that you receive from their so called "help desk".
