I want my money back !! Stop suspending my sim card for you ****** mistakes

I AM SO SICK OF MTN!!! IT HAS BEEN 3 MONTHS WHERE I HAVE BEEN BILLED INCORRECTLY WITH EXTRA R400 ON MY ****** BILL, MY SIM CARD HAS BEEN SUSPENDED TWICE ALREADY . MY INCONVES SHOW NOTHING OF EXTRA CHARGES NOR SUBSCRIPTIONS, THERE IS NO EXPLANATION OF THIS *******!! NO ONE IS WILLING TO ASSIST ON SITE

THIS COMPANY IS TREATING IT'S CUSTOMERS LIKE ******* , I AM ON HOLD YET AGAIN ON ALL PLATFORMS EVEN THEIR COMPLAINTS PLATFORM NO ANSWER , MY SIM IS YET SUSPENDED

DO NOT GO FOR MTN IN WHATERVER CASE !!!!!!!!
