Standard Bank never remove the life cover after proof was sent through twice

I have a home loan. I bought a property in end of 2014, and with the purchase I provided my current life cover policy. I have sent through all required documentation with the direct details of the person that handles my life cover. However, I never received statements, this last 2 weeks I managed to get a statement, after many calls to them, and to a shock the life cover premuim was not removed.

I can not believe that I did everything right from my side but Standardbank just ignored the documents and charged me about R350 extra each month for an extra life cover. Unacceptable.
