CHANGE OF PREMUIM WITHOUT NOTICE

I HAVE TAKEN THE POLICY LAST YEAR NOVEMBER AND THE INITIAL INSTALMENT WAS R1089 THEN IN JANUARY MY PREMUIM INCREASED BY R119 WITHOUT ANYONE NOTIFYING ME. I MADE A CALL THIS WEEK NONE OF THEM COULD HELP ME IN EXPLAINING BECAUSE AI SUBMITTED MY FITTIMENT CERTIFICATE ON TIME, THEY PROMISED TO CALL ME SINCE THIS DAY I AM STILL WAITING FOR THEM TO CALL THEM. I HAVE RECEIVED A BETTER QOUTE WITH ANOTHER SERVICE PROVIDER THAT IS WAY BETTER THAN THE 1ST ONE WITH YOU...IF YOU ARE GOING TO CALL ME, PLEASE BETTER HAVE THE EXPLANATION AND RECTIFIY THE ERROR AND BRING BACK MY MONEY. YOU GUYS ARE ****MER
