SUSPENDED ACCOUNT

MTN BLOCK AND SUSPEND MY LINES AND ACCOUNT FOR R4000.00 BUT THEY LET CELL C RUN UP AN ACCOUNT OF R393 MILLION WITHOUT BEING CUT OFF!!! I WOULD LIKE TO SEE THIS MATTER BE EXPLAINED. I GUESS THE MONEY THEY PAY WHEN THEY DO IS BETTER THAN MINE??? IM SURE THIS WILL DO WELL IN COURT ESPECIALLY AFTER TRYING TO RESOLVE THE ISSUE
