Vodacom agents don't cancel contracts-****** to get us paying even when we dont want

I had a contract with vodacom. Called and asked to cancel at the end of the year 2019. The agent promised to send me a quote on the amount that i'd need to pay for early cancellation. months went by and no one contacted me. Early 2020 i called again to say the end of the contract is coming to an end, i do not want to continue as i don't even know where the sim card is. Agent agreed but they carried on deducting my money.

Called them in January 2021 for days trying to the bottom of this but was changed from one agent to another. Told them the above and was told to i could cancel the contract immedaitley and that i they would credit the amount they claimed i owed them. After i had argued that they owe me all the money they've been deducting after i clearly informed them that i was not interested in renewing the contract. Today i check my credit report and Vodacom has taken me to credit bureau. I'm upset at the level of service I've received from Vodacom. NEVER GET INTO A CONTRACT WITH VODACOM, THEY ARE ******!
