Bad customer service

I have done a sim swap on 02 November 2018 and was advised that it would be active within 48 working hours excluding weekends and that they only work 8 hours a day, which I acceped and waited for the activation which then happened on the 7th November. Since then I cannot receive any calls, sms or whatsapp calls. I have bought and loaded the airtime and data bundles but my balance remains at 0.00 for airtime and data. I have been been calling their line since the 23rd. I was given a reference number ********** 846585 and told it will take another 48 working hours to be resolved. Their call center agents are unprofessional, they chat to one another or chew in your ear while you explaining your issue. I have made 6 phone calls which lasts 10 minutes a call today. I have spoken to Linda who eventually called me back just to be informed that she don't know how to resolve my issue. She will call back again. That was at 10am today. Since then I have explain the issue to Phindile, Mashudu (supervisor), Noluthando and Lebo to get Linda from their admin department to call me back with the progress of my query. Phoned again at 15h05 waited 10mins for the call to be answered. There is no direct number for the admin department. I am very irrate as this is my business number and I am losing out on clients who cannot contact me.
