Vodacom Lacks Customer Service

I am a vodacom customer, have been since I owned a phone in 2006. I have taken contracts with Vodacom and latest being in 2017 October . Here's my problem. I cancelled my contracts in 2020, they have records of those calls. I am still being debited. I went in store and was told my accounts are still active. They proceeded to say, ma'am remember it's a 24 month contract so you can't end it yet until October this year. Did I not get left puzzled, like did this gentleman do the calculations, were in the year 2021. My reasons for canceling my contracts were very plain and simple, what's worse is they can see it appearing on their system that I last used their sim card and benefits years ago because it shows accumulated amounts. I'm not being taken seriously here and I hate it at Vodacom such that I'm actually never going to ever advise anyone to take a contract with them. They make the system so frustrating and don't care for how they are inconveniencing you in the process. At this point, they can chuck away my points accumulated, I want nothing to do with Vodacom and don't even care for being a loyal customer. I'm exhausted and frustrated all because of a contract from 2017,no upgrades even.
