Vodacom please cancel my contract immediately

I am so so angry with Vodacom. I called into vodacom way in time to cancel my contract when it end end of October. The lady even confirmed that I should finish all my data before the end of the month and to my surprise vodacom loaded the data again. I called in yesterday and spoke with a very rude guy who first tried to sell me new products, I informed him about my woes with vodacom and told him I had had enough and since the contract has ended and I already canceled, he shud make sure it happens. He spoke while I was speaking prevailing over me that he can schedule the end of the contract for end November as there is no cancelation logged on the system. I will not accept that shame as I did what I was meant to do. Vodacom can go access the recordings from the last two times I called in, I am not paying another month more and this must be fixed. It's not my fault the lady didn't do what she was supposed to do as instructed by the client. Vodacom you must fix this, and I will not be disrespected again like that imbecile I spoke to yesterday. Please cancel that contract immediately before I lose my mind!!! Nxa
