I recieved a call this morning from a supposed account officer that called himself Michael Adebayo asking why I refused to respond to the message sent from my bank last week.
I asked for the bank in question, but he quickly waved my question to read out my BVN and phone number which are surprisingly correct.
He asked if I remembered the bank I did my BVN registration, of which I answered negative and since he knew my BVN and phone number, he should be able to know the bank I registered with.
I asked for the bank he was calling from, and he answered "First Bank".
I told him that he is a Fraudster, he called me a fraudster too and ended the call.

Please be careful not to fall for their antics of calling your BVN. They are fraudsters, no bank will call you or send you Sms asking for any information regarding your account. Bank will always ask you to visit any of their branch to resolve any issue related to your account.
