Cannot cancel vodacom bundle

I have cancelled a recurring bundle 4 times with vodacom. The first 2 times, vodacom reinstated the bundle without my knowledge. The third time I went to the store in Gateway theatre of shopping and on the 25th of March 2022 and cancelled it but they only cancelled one bundle on another number. I called in on the 9th of May 2022. I even have an sms from vodacom stating that it was cancelled. it wasn't cancelled. I called in again on the 7th of June 2022 to cancel again. It wasn't cancelled. I called in again on the 4th of July 2022. It is till not showing cancelled on their system. I am being billed for a service that i do not need and have no other way of cancelling it.
