Deducting insurance after policy is stopped

On 18-03-2016 I arranged with ABSA to stop my building insurance. I was informed it takes 3 days to do the changes and reduce my bond repayment. I duly received an confirmation e-mail from Absa that the request has been received at 14h54 on this day. This was after I submitted my proof of new policy in my name for this property.<br> <br> Now 19 days later Absa decided they want more of my money and went ahead to deduct insurance together with my bond payment. I wonder how long would Absa continue to deduct money not owed to them for any service rendered.<br> <br> Trying to phone is a nightmare as at times the phone is not even answered. Going to a branch does not help as Absa branches distance themselves from insurance complaints and it is up to the customer to sort out the in house problems.
