Wesbank deducting comprehensive insurance without authorisation

Good Day. I need assistance please. I took out vehicle finance with Wesbank in 2022. Recently they have been sending me an SMS requesting for my car's comprehensive insurance cover. Currently I'm out of the country for work and will only return to South Africa in April next year and I cancelled my cover when I Ieft the country in June coz the car in question is not in use but locked in a garage. I will resume my cover when I get back next next year, one thing I do not want is for Wesbank to be deducting money for an insurance I did not agree to like the last time. I did reply back to the email and no one has gotten back to me and I definitely do not want their unauthorized insurance cover.
