No Customer Service

I requested that 2 data contracts which was up for an upgrade be cancelled at the end of August, the one contract was cancelled but the other was not, I then noticed that my account was debited at the end of September, I called again and the agent guaranteed me that the contract will be cancelled, once again at the end of October my account was debited again, I tried calling today(31/10/2017), this was around 11:30 and according to the agent the systems are down, I then tried calling again at 13:30 and it took forever to answer and finally when the agent picked up, the call was cut. After me cancelling the same contract twice and my account still being debited I would say this is theft, very unhappy with the pathetic service of Vodacom
