Cancelled Car Insurance

I have had car insurance with Broker Buddy under Khetha insurance since July 2021 and have never had an inpaid premium.

This month, due to an emergency, I reversed my debit order with the knowledge that I have 15 days to make the payment before my policy lapses. I contacted them and informed them thay I reversed the debit order and they should please resubmit the debit order.

Days later, I got an sns that said My Insurance was cancelled and I should be requoted for a new insurance, their reason is that the policy I was on no longer exists and therefore I need to get a new insurance. How do you cancel a policy just like that when I requested withhin the timeframe that it be debited again? How does my insurance package no longer exist? Now Im left stranded without cover for my car because mine no longer exist. I am not happy at all!!!!! I woukd like my car insurance reinstated please.
