Vodacom network not working - vodacom 'don't know how to help'

I have been a loyal Vodacom subscriber for many years. I have had trouble over the last few months with unauthorized changes to my account, debit orders going off of almost double the amount on the bill and then having to wait 3 weeks to be paid back and then getting a BILL of R141 for CREDIT NOTES!!! And the worst of it is that NO ONE is able to assist me or tell me what's going on!!! This week Vodacom has definitely outdone themselves! On Wednesday 25 July2018 as I was walking away from the office – away from the Wi-fi – my phone suddenly stopped working. My mobile data wouldn’t work, even thought there was still over 800Meg available and my phoce has a message saying ‘Emergency calls only’. When I tried to phone the Vodacom helpline,even that number wouldn’t work. I finally called 082 111 on a friend’s landline. They couldn’t help me. Finally I went to Vodacom Chatz in Gezine Galleries – who were extremely friendly and did everything they could to try to help me – where they found that a sim swop was made on my phone. I never asked for one and did not authorize one either. A total of 3 sim swops was made, one after the other and there was a cancellation pending…??? The lady gave me a new sim card and told me I had to wait 24 hours for the cancellation to go through and then another 4 hours before I insert the sim card. It didn’t work. I went back on Friday 27 July where they gave me ANOTHER sim card after testing the sim card on another phone – it did the same on the other phone – and did another sim swop. Again it did not work. Yesterday, Monday 30 July, I went for the third time. Once more they did a sim swop and gave me a new sim card. I waited almost 5 hours before turning on my phone. It still doesn’t work. I am without any communication and as a women having to go somewhere without a phone for emergencies is looking for trouble. I have no way of contacting anyone or of being contacted. It has been a week and STILL VODACOM IS UNABLE TO HELP. Please get back to me and sort out this problem. I am VERY unhappy with Vodacom’s service!
