CHARGED TWICE FOR ZERO NETWORK COVERAGE BY RAIN.

I HAVE BARELY HAD ANY RAIN INTERNET THE PAST TWO MONTHS YET THIS IS THE SECOND THEY ARE TAKING MY MONEY . 500 RAND IS A LOT OF MONEY TO BE TAKEN UNDER "MONTHLY DATA BILL" YET THE NETWORK HAS NOT BEEN WORKING NOT EVEN ONE MB OF CONNECTIVITY . NOW ITS 1000. IVE TRIED TO CANCEL ON THE NUMBERS PROVIDED I DO NOT SUCCEED. TO REMOVE MY CARD DETAILS , IM NOT WINNING EITHER. THIS IS UNACCEPTABLE. I CANT EVEN CANCEL THE SIM AS IT SAYS IT WILL STILL CHARGE ME, I WANT OUT AND DEMAND A REFUND RAIN .
