Unjust insurance cancellation

I was involved in a car accident on the 13th of January 2025. Whilst at the accident scene I was asked which insurance company I use and I told them Santam, however Santam claimed they couldn’t find my profile, upon calling them they referred me to my broker and he was not available to assist. After numerous attempts they called back to say they made a mistake they confirmed that they debited my account on the 3rd January, after this call I called them back to arrange for a courtesy car, but to my disappointment they again refused to help and referred me to my broker and I was left stranded without a car or any assistance. Days later upon following up I found out they had cancelled my insurance with my broker and none of this was communicated with me, to date this has not been resolved, I am without a car and still paying for the it, Santam refuses to take accountability and the broker is also unable to assist.
