Absa
I am being debited a premium I did not authorise

I bought a car in september 2012 financed by Absa and my insurance was First for woman. November 2012 I changed my insurance to Mutual and Federal. To my amazement absa is debiting my account and paying an insurance premium at First for woman while I am paying my car's insurance premium at Mutual and federal. They now say I am in areas. How can I pay two insurances for one car.
