Vodacom is the worst

I have been using Vodacom network for years now and just recently on the 15th of May I did an upgrade from 20gig data deal to 100gig, on the 1st of June the day I receive my data i got a message from them telling me my upgrade has been approved and I'll be paying R6 in addition for insurance then that was the last time my Sim card had connection, it completely stopped working. I went back to Vodacom shop where I app**** for my upgrade to query and they told me my Sim has changed I can no longer place calls or receive calls it can only be used for data usage only in my router, OK, I went back home inserted the Sim on the router the Sim was not connecting still showing red light only. I then contacted customer care they told me it must be network coverage as it seems to be nothing wrong with my connection on their side so I should wait for at least a day, I waited. On the 2nd of June still no connection I called them again I was told maybe my Sim is damaged I should do a Sim swap, I went to Maponya mall on the 3rd to do a Sim swap but it's still not connecting then I called customer care again, they told me maybe the new sim I had just done Sim swap on is damaged straight from the store so I should do another Sim swop. This is on the 4th, I did a Sim swop from Mall Of The South for the second time and still is not connecting. I'm now told to wait 24 hrs until the technicians respond as they have escalated the issue. Mind you it's been 4 days without connection and with no concrete solution, everyone I spoke to seems to be thumb sucking where the problem might be and I'm expected to pay R460 every month end.
