why were my covers cancelled and why am I still paying for them then?

When I buying my car Wesbank had convinced me to take extra insurance such as the service plan and Coverplus. I was involved in a car accident in February, my car was ready a few ago and it was time to pay the excess, I tried to claim and Motorite notified me that wesbank has cancelled my cover.

1. why wasn't I notified? 2. why am I still paying monthly payments which include the extra insurance attached to my monthly instalments

when I confront the lady I usually deal with(I will respectfully not mention her on this platform) I'm told "that's no longer my department"

this is unacceptable and you don't treat people this way
