Still billed for Insurance

I went to ABSA bank in Kuils River in December 2015 to cancel my insurance on my personal loan. They however did it and asked that I should go back to Stellenbosch and asked the consultant who opened the loan account for me to cancel the insurance. In January I was billed again for the insurance and went back to Stellenbosch. Apparently the consultant at information asked the manager to cancel the insurance which apparently he did. This month I got a statement from ABSA which state the instalment including the insurance. This is totally unacceptable. I need this matter to be fixed please.
