Wesbank & Direct Axis : Bad customer service & debited incorrectly for comprehensive cover

I was issued with a letter for DA outstanding debt for comprehensive cover for my car, so I will now be debited monthly, as according to the wesbank /direct axis group I do not have comprehensive cover....(which I do which I emailed) but im still getting debited....I am mortified that I have been struggling literally 100s of times to get hold of any customer service agent to stop this debit order...Waiting for 45mins and longer for agent still not to get through.

Sending emails continuously with my PROOF of Comprehensive cover on my car. But still nothing.

Except they had the audacity to send me an email in the early hours of the morning explaining what their comprehensive cover actually covers.

So I must just accept that incorrect debits coming off my account and there is absolutely NO WAY OF CONTACTING THESE COMPANIES, NO CUSTOMER SERVICE, NO EMAIL RESPONSES?

is this normal behaviour from financial institutions!
