Santam cancels insurance without ensuring that I know about it

After being a client of Santam since early 1990s, I today (24 November 2020) got a letter that has possibly been in the mail for a few months...notifying me that my short term insurance has been cancelled due to 'admin changes' on 2 July 2020. The letter was created on 3 July 2020. The letter recommends that I arrange other short term insurance to ensure that my assets are covered.

How is this possible that Santam cancels my policy, without any acknowledgement from my side with a mailed letter claiming to give me 30 days written notice, that clearly states that it was created a day after the cancellation date.. AND then the debit order for the montly payment is still deducted every month.

I will definitely conctact the ombudsman about this lack of service and integrity.
