Disgusted and Appalling!!!!

Good Day, I moved insurances almost 3 years ago and am paying R919 for a 2008 s40.My sister has a 2020 xc60 and pays R750.00 for her insurance, MY CAR IS 14 YEARS OLD and I pay more. I emailed absa requesting a review of my premium as the car is old and has depreciated .Absa calls and advises they can reduce to R799.00,A whole R120 in almost 3 years. I asked if they can better this and was told NO...It increased every year although the car depreciated. I asked the agent, does the review get done every year as my premium has never dropped and was told that ONLY IF YOU CALL IN, So if you have insurance for 5 years and never called in, you premium will go up every year even though your car has depreciated. WHY ABSA...........WHY do you do this to your customers? So much competition out there and you here robbing your customers. PLEASE ADVISE IF YOU CAN BETTER R799.00, or should I move?
