Enquiries is exceptionally rude!

I called in to customer services to enquire as to why Absa Bank was charging me almost R500 extra a month on my car installment. I cancelled my car insurance due to the fact that I wasn't using the car anymore and Absa added their own Insurance to the car and was charging me for it every month (WITHOUT NOTIFYING ME).<br> <br> I called to enquire about this extra charge and the woman was exceptionally RUDE and BLUNT with me.<br> <br> This is completely unacceptable..! I want a refund for those months where the insurance was billed to me without my Concent!
