How much do you have to invest? For how long are you willing to invest? What are your reasons for investing?Send your phone and response to this mail I may further the discussion with you: positivetimmy2@yahoo.com

Sorry about that, it is because you are new not current in the system. That is the stock in trade of most of the new generation banks. They dont lend to start or grow any business in Nigeria. What they do is to pull the money together and use it to do their own business or pursue their business interest. Unfortunately, none of the regulatory bodies is interested in check mating such practises. With the exception of the old generation banks, we dont have banks in Nigeria, what we have are cash keepers.
