Sanlam doesn’t want to cancel my policies

I have been with Sanlam since 2022. I had life cover, salary protection, accident and death cover with them. The agreement was that this will go up every year in January as my salary goes up. Cool. I agreed, signed everything, provided a beneficiary. All was cool. Never missed a payment. Then out of the blue I receive a message from my bank, Sanlam has pulled more than usual, I am like ‘how’. It’s not January. I try to contact Sanlam, send emails, no response. Eventually I call them, and the agent says “oh mam we are sorry, we did not have your updated information”. What updated information? I have had the same number and email all working life. From then on, I asked for a cancellation, rather early than late. I tell them, I want a cancellation, and what do I suddenly get emails requesting me to update my information. Why? When I have already said I want a cancellation. It is trouble. They sure had my correct banking details. Please cancel as a matter of urgency, I have said this many times already.
