REFUND DEMAND!!! PATHETIC SERVICE!!!!!

I cancelled my contract within cooling period of 7days. I was debited a pro rata amount of R199 of I have questioned and was advised that it cover for Jan 2021. An *********** manager at Mall Of Africa advised he will revert to me regarding my cancelation of which that never occurred as I still took it upon me to go to the store regarding the status of the cancelation...was advised it was cancelled wand they took their minutes back and the sim was blocked. To my surprise today I woke up with a debit of R372... WHY THE HELL WAS I DEBITED FOR?????? I DEMAND MY MONEY BACK BEFORE END OF BUSINESS TODAY!!!!!!!!!! I AM JADED WITH YOUR INCONVENIENCE. BELIEVE YOU ME THAT I WILL TAKE THIS TO CONSUMER LEGISLATION. MALL OF AFRICA MANAGER IS PATHETIC AND HAVE ATTITUDE AND BAD CUSTOMER CARE SERVICE WOULDN'T RECOMMEND ANYONE TO TAKE CONTRACT WITH CELL C
