ABSA Vehicel insurance

I write this as I am deeply dissatisfied due to empty promises from Carol May of ABSA Claremont. This stems from my vehicle insurance premium not being adjusted for the last 2 years. I have repeatedly spoken via telephone and contacted her via e-mails stating that my premium of R650 p/m has to re-adjusted. I have had this vehicle for three years and we all know that the value depreciates annually. I have been a valued client for over two decades since the days of AL**** Bank. I would have thought that I warrant some better service. I do realise that I am but one insignificant client but I am now considering alternative companies for vehicle insurance. I have in fact lost monies had my insurance been adjusted when I requested it to be. The latest promise was that it was sent to late to the billing department. I am at my wits end and hope this makes someone listen to my plight.
