MR PRICE FALSE ADVERTISING *********** BRING BACK MY MONEY

LAST YEAR, I WAS CALLED BY A SALES AGENT FOR MRP. THEY TOLD ME ABOUT MR PRICE MOBILE AND THAT AS A LOYAL CUSTOMER THEY WILL BE SENDING ME A MRP SIM CARD. THIS SIM CARD IS A *FREE* PREPAID SIM CARD, WHICH WILL BE ACTIVATED ONCE I START USING IT. THE SIM WAS DELIVERED AND I HAVE NEVER ACTIVATED NOR USED IT. I AM BEDAZZLED WHEN I SEE R100 OFF MY MRP ACCOUNT WRITTEN MRP100. HERE I AM PAYING FOR MY ACCOUNT EVERY MONTH AND THEY ARE CHOWING MY MONEY FOR FALSE ADVERTISING ON THEIR BEHALF. PLEASE ADVISE HOW I CAN RETRIEVE MY MONEY BACK , MRP MUST BE PENALISED FOR THIS!!!
