text: If you are asking abut a bank in Nigeria, I am guessing that you have been approached by someone working a "419" scam - if you help them with their delicate financial problem, they will give you millions of dollars....  Do NOT give them any of your personal information (phone numbers, addresses, bank account numbers, social security number, etc.).  If you have already lost money, you can try contacting the US Secret Service, but it is unlikely you will ever see your money again.
