Sim swap nightmare!

I am absolutely livid! Been trying to feedback on on a sim swap for more than a week now. I have spent hundreds of Rands, wasted hours on the phone listening to music just to get my calls cut. There is only one number to contact for assistance but you are never assisted in any way. My mom's phone was ****** 2 weeks ago, it's been a nightmare trying to get a sim swap actioned. We have been sent from pillar to post between Vodacom and Jet stores, only to be told oh we can only email RMCS to request the sim swap but that's about it. Absolutely appalling customer service, was advised a turnaround time of 3 working days, it has now been 6 working days. I need urgent assistance! My mother needs a working number! This is ridiculous! We will be canceling this contract really soon and will never recommend anyone to enter into any contract with RMCS.
