Termination of contract

According to me my contract is expiring in January 2022, so I phoned in now to give notice to cancel it. I was then told that my contract only expires in April 2022. The lady told me she can't see when it was first taken out, all that she can see is that it was suspended in 2019 and therefore the extension to April. I have never suspended my contract, I've been using my data every month and paying my contract. I've been speaking to 2 customer care consultants who said I need to speak to collections. Collections says that I need to speak customer care as my account was never suspended and they need to rectify my termination date. This is unacceptable and terrible to say the least. I experienced a lot of trouble when I took out the contract and now it's the same thing and that is why I want to terminate my relationship with Vodacom. A lady at customer care now logged a query for my termination date to be rectified, reference number ***, and they will get back to me within 48 hours. Not believing them at all as they under deliver on promises made. I am furious to say the least. I will take out a Vodacom contract again.
