Absa Idrect Insurance

I have been trying to get into contact with Absa Idirect regarding my insurance premium on my vehicle for over 5 weeks now. Even after numerous emails (which confirmation of receipt has been confirmed with a reference number) and not to even talk about the calls to their 0860 number, which NOBODY even bothers to answers the calls which you can hold on for up to 38 minutes! I've NEVER in my over 20 years having insurance had such BAD/UNACCEPTABLE service from a company. Even after writing an email to cancel my service with Absa Idirect, they still deducted the premium nonchalantly. Please can someone assist me in this matter or tell me whom I can contact to rapport this
