Vodacom has been taking my money, for no reason!!!

My account has been deducted for the past two years, without a renewed contract. I'm not even in South Africa and there is no way for me to cancel this debit. Countless emails were sent and all they respond with is the AI Tobi, who can do absolutely nothing for me. I signed a 24 month contract in 2021. I did not renew, after the phone amd contract was paid up. Yet, they jave continued to deduct monthly the R600 from the old plan. Make it stop, because now you're just *****ing money and choose to not respond to my emails. They can clearly see from their records that the number is inactive and no top ups have been done on it for months. Vodacom, stop taking monies that's not yours ans cancel this unsigned contract officially.
