Re-activation

I was without work for two months in that time period i requested that MTN cancel my debit order, we agreed that monthly i would pay via EFT. at the beginning of April i have been blessed with a new job, i tried calling MTN but after holding for more than what seems forever someone finally answered my call advised that i make a payment for April send proof of payment and they would re-activate my account and let my account go of via debit order, it's been a week later no debit order and now my phone has been barred. i can only receive calls and SMS, however even though i purchased airtime i cannot call out or receive whats apps emails etc. i am due for an Upgrade in June thus far i had no hassles with you guys but seems like i'll wait till August and cancel the blooming contract.
