someone called a friend of mine yesterday. he told him (my friend) that he is a staff with Firstbank headquarters in Lagos. he then told him some detail informations about his account which were very true. this made my friend to agree that it's a Firstbank staff. he informed him as well that the date of birth in the bvn is not the same with the date of birth used in opening the account (this was perfectly true because my friend knew the problem in his account). he then told my friend that they (Firstbank) are about to resolve the issue for him so he should call out the numbers on the ATM card to him which my friend ignorantly did... my friend called out this number together with the expiry date and the other three numbers on the ATM. I know it was out of trust already established by the true informations given by the guy who claimed he is a staff. after a while, my friend got a debit alert from first bank, all the money in my friends account was wiped off.
right now we are ready and about to visit the court to sue Firstbank because we feel a Firstbank staff must have been involved in the fraud, if not, how did he get the detailed information he gave my friend?

please I need your views on this especially on the step we are about to take.

thanks so much.

you cant win such case, all banks have warned their customers never to give anybody their atm card and pin, be it a bank staff or not.

but don't you think it's a crime to give fraudsters details of customers account?
I think there are laws from CBN which applies to all banks in such cases.
