This number is a scam. First, they offer to loan you a sizable amount. Then they tell you that in order to check out your bank account anf trust worthiness, they will deposit a smaller sum into your account; but, and here's the catch, then you have to transfer than some to a third party. In reality, the amount that they deposit into your account is a fraudulent mobile bank deposit using a stolen of forged check.
They call themselves Comman Wealth Finance, but note that this isn't Commonwealth Finance: Its one letter off.
