My MTN Contract suspended

<p>Last month I upgraded mý cellphone. I also requested that the debit order deduction, that used to be on the 15th of every month, be moved to the end of the month.. Sadly MTN debited my account on the 15 th of November 2016. Seeing the MTN Tax Invoice sent to me is confirming that the instalment will be debited on the 4th of December 2016, I stopped and reversed the debit order that was not in line with the invoice sent to me by MTN. I expected MTN to debit the amount on the 4th of December 2016 as per the invoice sent to me. Unfortunately they did not honour their invoice debit order. Funds were available. But MTN opted not to debit my account. MTN has thus suspended my cellphone number. </p>
