BEWARE OF MTN. LOUISE NCUBE MTN

Mtn double debited my Fnb acount with an amount of 4666.70...my normal cell acount is 2322.00 per month. i have contact louise Ncube at Mtn and written her several letters but looks like these letters have fallen on deaf ears. what Mtn doesnt care about is that i have just enough money in my account for my debit orders and by Mtn double debiting my account i now have returns on all my debit orders....now giving me a bad credit rating with itc.
