credit,your are now left with only 0.00naira, remember that if you
recharge 100naira they will deduct the 100naira meaning that you just
paid the amount you borrowed.

Simply recharge the 100naira you want to use for the payment by
dialing *885*YourRechargePin#
With this you have automatically paid for the 100naira you borrowed
and still left with 100naira Bonus.
