Not able to cancel Fibre contact

I have been trying to cancel my Vodacom Fibre now for over a week, and nobody at Vodacom know what is going on. I logged a request on the 6th of July to cancel my contract, which after 2 years has gone to a month to month. my reference for this is SR***5.-7987 I was told this would be allocated to the cancelation team within 24-48 hours, after speaking to Max, Mustapha and Sarah, all of which have different ideas of the cancelation process and Max and Mustapha caught lying to me, I eventually loaded my complaint of Facebook. today I received a call from Sabastian who "seemed" to know what he was talking about and told me in our conversation that my request was escalated and he was a superior who would make sure it gets allocated. also what he told me was that since I cancelled on the 6 of July, my last payment would be at the end of July. I ASKED HIM TO CONFIRM THIS ON THE CALL WHICH HE DID. I have now arranged for my new network to be set up from the 7th of August, giving Vodacom their 30 day notice. I have just been informed by Sabastian ( who is a superior in the cancelations department ) that he also does not know the process and that I now need to give a calendar month notice, so will be liable to pay for service up to the 1st of September please can someone train the staff at Vodacom the correct procedures as not even supervisors are taught their jobs I have been with Vodacom for over 20 years, and because of this I will be canceling my cell phone contract this year as well. absolutely terrible service, I would much rather deal with a Government institution than Vodacom Because of their incompetency I will now have a double fibre bill End of August, but hey, they don't care
