MTN is ****

MTN is so bad. they failed to debit my account when i opened my contract 11 Months ago. so Now after 11 Months they double debit me, NO COMMUNICATE NO ANYTHING they just debit and say nothing. I have been struggling for 3 Weeks for someone just to give me a answer or call me but nothing all i get is Staff from MTN emailing me with stinking attitudes. I WILL ADVISE EVERYONE I KNOW NOT TO TAKE ANY CONTRACTS WITH MTN.
