Still disputing huge bill

Utterly Disgusted: For 17 x Months my account was perfect. 1 x Month two of my MTN cellphone numbers ran into the R6 500.00 each. How is something like that possible if I always had to load data on the account. MTN is not even willing to look into my history. Really??? Please give me proof that my account looked like this before and only then will I not complain about how bad and poor service gets from MTN? <br> <br> I WILL KEEP POSTING THINGS ON HELLO PETER UNTIL MTN LOOK INTO MY ACCOUNT AND LET ME KNOW WHY MY ACCOUNT WENT OPEN FOR 1 X MONTH. FOR 17 X MONTHS THE DATA WAS CONTROLLED BY ME ON THE ACCOUNT. 1 X MONTH I GET A HUGE ACCOUNT. THIS IS SO UNFAIR TOWARD ME AFTER I REQUESTED TO ADD A USAGE LIMIT TO MY ACCOUNT. WHY MUST THE CLIENT PAY FOR MTN'S STAFF THAT CAN'T DO THEIR JOB. NUMEROUS E-MAILS AND STILL NO DECENT RESPONSE FROM MTN. LOOK INTO IN AND LET ME KNOW WHY MY ACCOUNT WAS ALWAYS STABLE (R1 200 PER MONTH) AND 1 X MONTH GET A BILL FOR OVER R13 000.<br> <br>
