Horrible service

All the paperwork was done for my fibre contract to be cancelled on the 31st December 2018. Vodacom billed me for 3 more months. I called them a few times every month and ask why did they billed for for 3 extra months. No answer. They keep telling me Dominique is investigating. No one is calling me back to tell me what's going on. My account with vodacom is over R8000 every month. Im going to cancel all my contracts as soon as the contract period is over. I've never received such bad customer service. I wonder if Vodacom would be happy if i owed them over R2000 and did not pay

I've written a review a few days ago and no one has even bothered to call me back
