CANCELLED MOTORITE POLICY WITHOUT MY CONSENT

My wife has a maintenance policy schedule that states that it expires in July 2025, that was taken via Standard Bank when she financed her vehicle in 2020. She was, however told this morning that it has been cancelled allegedly by the bank with no trace of this and without her consent. Now, one can imagine how UNACCEPTABLE this is. This needs to be resolved immediately! We have been sent from pillar to post and nobody knows the cause of the issue and how to resolve it, yet we are continuously being debited with no issues. WE NEED THIS RESOLVED URGENTLY
