DEDUCTING WRONG AMOUNT AND NO CUSTOMER SERVICE

All MTN can do good is phone you to upgrade or take a special but when it comes to customer service they BAD VERY VERY BAD. I have been trying to sort out why they deducted a wrong amount from my account and all they can say yes its wrong but they dont fix or reply back to my email. I will never ever deal with them again. STAY AWAY FROM THEM
