ANNOYING SERVICE VODACOM KENAKO PORT ELIZABETH

I BOUGHT A CHARGER AROUND 10/12/17 AT VODACOM KENAKO MALL IN PORT ELIZABETH WITHIN 2 WEEKS IT DIDN'T WORK. I SENT IT ON 29/12/17 AND WAS TOLD IT'LL BE SENT FOR REPAIRS AS THEY CAN'T EXCHANGE FOR CASH. I'VE BEEN GOING THERE SINCE JANUARY AND TOLD DIFFERENT STORIES I BOUGHT MYSELF ANOTHER CHARGER AND I WANT MY MONEY BACK AS I DON'T WANT ANYTHING FRO M THEM. WHAT'S WORSE THE MANAGER LAST WEEK SAID IT'S THE FIRST TIME SHE HEARD ABOUT THIS MATTER WHEREAS I'VE BEEN THERE SINCE JANUARY. HEAD OFFICE GAVE ME PE NUMBER AND THAT NUMBER TOLD ME THE NUMBER FOR COMPALINTS CAN'T TAKE CALLS. THIS IS REALLY DISGUISTING ,PATHETIC AND ANNOYING SERVICE FROM VODACOM
