I mistakenly recharged 50k airtime from my Firstbank app instead of 500naira

Hi Ahmad, you need to contact MTN support for assistant, they will reverse the unused balance to the correct phone number if the airtime has been tampered with on the wrong line...

Hi Adebisi, to reverse wrong amount recharge or subscription to your bank account, you need to contact your bank or your point of purchase with the details of the transaction...

I made mistake by recharge 20,000 instead of 5...
