Unauthorised debit orders

Hi,

I hope you're good.

I took out a contract from Vodacom about 3 years ago. It was insured through Vodasure / Vodasur. After my contract ended and was terminated, Vodasure never stopped taking money from my bank until I recently stopped it myself from the mobile App. By recently I mean in Dec 2021 or Jan 2022.

I made a call to Vodasure and they denied having my profile on their system. Upon going to the bank to find out exactly who this is; it was confirmed its Vodacom Insurance.

Can someone assist me with this as I would like to get refunded.

Thank you
