Unfair and Poor Service

I upgraded my Vodacom contract in 2019 Aug, I never used the sim card. I paid R199 p/m. 2020 Jun I lost my Job, I was unable to pay full amounts for some months, I only skipped one month, and the rest of the month was paying in half. Contract is supposed to end this year, Vodacom is telling me that the contract was extended until Aug 2022. I spoke to an agent on the 24th of July 2021, they confirmed that outstanding amount was R440.05 and that if I pay that, I am able to cancel the contract. Now when I enquire the status of my account, they extended to another year.

Reason being my account was suspended (no one never told me) What was i paying for from last year until now? I am fed up with Vodacom, i have never used the sim card. Now they say to cancel i must pay an additional amount of R1350. for what? The contract was for 2 years, not its 3 years? how?

Hello Peter please advise, I'm not working a full time job as I was, how will I afford an extended contract? I was under the impression that a contract is 224 months?
