Vodacom don't care to fix their own mistakes

Vodacom has loaded my home internet service on my cell phone by their own mistake. Unwilling to migrate or correct their mistake. This has made my day to day business unbearable!!! 4 months now! Zero progress. I can't make or receive calls, no sms, no OTP pins, my phone is useless now. Data only. They promised to pick up the home internet wifi router and to cancel their mistake. No one showed up. I have no alternative but to find another provider and to cancel everything with Vodacom... and then I'll also be forced to pay penalties. I want to cry!!!
