When you ask the bank why they close your account, whether their answer? In my opinion there is only one reason why the bank closed the account of the person, ie since the bank go bankrupt. In my country there ever bank that went bankrupt and closed more than 1 million accounts of customers and amount to trillions. I personally still believe the bank because I am sure the bank that I chose is a bona fide bank. You can sue him in court if you do not make mistakes that lead to your account closed.
I had the same believe as you did, until this misfortune happened to me. In fact, tens of millions Americas don't own a bank account at all. They cash their paycheck at payday loan stores or check cashing agencies, which have more locations than McDonald restaurants. People are losing faith in banks.
Honestly I just know from you. Perhaps we are in a different country so I do not know more. Because in my country there are still many people who believe the bank and all of the salaries received by the bank. But I still want to know even more, and you have not answered my question ... when they close your account, what are their reasons? I'm sure they have a reason and I want to know. It was a very large amount and I think you could ask for legal protection from the government.
