Vodacom not honoring term agreement

Hi Vodacom.

Can someone please assist me with this issue I'm having? I'm still getting billed for a contract I took out on the 16th of December 2017. The contract term agreement was for 24 months, therefore my contract ended on the 10th of January 2020. I called the accounts department and spoke to a consultant that referred me to customer care, calling customer care I get the same prompt options that gets me back to the account department.

I feel like this matter is going nowhere and I'm still getting billed at the end of every month.

Please sort this out!
