Vodacom is the worst service provider

I called in on the 28th of September to do an online upgrade. On the 4th of October while I was out my phone was suddenly not working. None of my apps worked and my calls were inaccessible. I then got back to my fibre at home and found that my account had been incorrectly debited with the cost of the handset for R28k and since then everyday I have been soft locked out of my phone unable to access my apps and unable to make calls even with enough minutes and data. No one at Vodacom is helping me to resolve this issue even though I cancelled the upgrade and returned the device. I have to call in every day to unlock my phone and speak to a new consultant to explain my problem even though this is their mistake. I am beyond frustrated and disgusted by their inability to give me feedback and their atrocious lack of customer service. I have been a customer for over 15 years and to be treated like this is horrifying. I could not use my GPS while out and got lost and had to turn back home. I was unable to call anyone. This is endangering my life and no one at Vodacom seems to care to resolve this.
