Vodacom

My Vodacom wifi contract expired on 9th February 2024. I called them in January and told them I wish to cancel contract on expiry date. The agent told me that's all in order and last deduction would be at end of February. March month end I see Vodacom deduction on my account and I promptly reversed it. I called again and told them that contract has expired and please cancel stop order, which they did. Since then I am constantly getting reminder that I'm in arrears with my Vodacom account and it has now been handed over to collection attorneys. I've since mailed attorneys and told them contract has expired, but their reply is that Vodacom says it's still active. I'm now suck and tired of this constant harassment and if they wake up and check then they can see that I have not used the wifi since expiry date. These service providers are all the same, they employ idiots and refuse to lose a customer. They can take me to court and I will counter claim for harassment
