Vodacom Bad Service Ever

Again, Vodacom making me look stupid... on my last review I stated that I called them to cancel one of my contracts as I do not wish to continue with their services. I said it here that they will not cancel as I asked. They called me and confirmed that it has been cancelled. But guess what it was not cancelled meaning I have to pay for something I have told them I don’t want anymore. I called them on the 05th of this month to check why they didn’t cancel, my call went back and forth and I was on the call for 1 hour 27 minutes being transferred from one department to another without solving my issue and I was told that they sent my query to the cancellation department for them to do their investigations and they will call me back. Even today I am still waiting for them to call me, I ended up calling them again today but to be transferred to the retentions department and the lady just said hello and I was put on hold for 12 min 39 sec. What I want to understand is why do I have to suffer when it come to Vodacom and have to pay them at the same time? their service is very bad………
