Worst Service Ever

In December I wanted to upgrade one of my data lines as it was due for an upgrade, However – Vodacom went an move my main voice line to a home internet service , so for the whole of December I couldn’t use my phone, and when I phoned the call center I was promised that my line will be moved back to the voice service that I had ..I needed to give them 72 hours ..which was a lie .. then they blocked me from calling the call center… line was only move back on the 1st of Jan 2024 not after the 72 hours…now that I didn’t pay for the services and only paid for the device for December ….Vodacom is sending messages that they are going to cut my services …how can I pay for home internet services that I couldn’t USE ??? and when I call the customer care line, they just transfer my calls, and it cuts ……my bill is over 2.5K a month and Vodacom want to cut my line for R199 for internet that I didn’t use?? What service is this to the customers???
