UNACCEPTABLE THREAT FROM VODACOM

i am ABSOLUTELY HORRIFIED BY THE SERVICE THAT I HAVE JUST RECEIVED FROM VODACOM, I GOT A CALL FROM VODACOM TELLING ME THAT THE PLAN THAT I AM ON WILL BE DISCONTINUED FROM THE END OF THE MONTH AND THAT FOR EXTRA MONEY I CAN GO ONTO THEIR NEW PLAN, I SAID I DONT WANT TO SPEND MORE MONEY ON MY CELL PHONE AND I WAS TOLD THAT IF I DONT MOVE OVER THEN I WILL LOOSE MY CURRENT DATA AND MY SMS - ***!!!!!! HOW CAN THEY PUT A GUN TO MY HEAD LIKE THAT IT IS TOTALLY UNACCCEPTABLE, THE LADY SAID TO ME, DID VODACOM NOT ADVISE ME OF THIS WHEN I UPGRADED I SAID NO , I HAVE BEEN TOLD NOTHING ABOUT THIS AND HAVE JUST UPGRADED MY SONS PHONE LAST WEEK AND NOBODY ADVISED ME OF ANYTHING - I CANNNNNOT BELIEVE THIS, I AM SO LIVERED THAT I WISH I COULD CANCEL THIS CONTRACT ALL TOGETHER WITH VODACOM, HOW CAN THEY THREATEN A CUSTOMER LIKE THIS - TAKE OUT THE NEW SERVICE OR ELSE - UNACCEPTABLE VODACOM
