Give us more information about the closing of your bank account, I guess they will not do that without any valid reasons though I don't have bank account yet but it's really normal if you do something illegally and don't respond to them about that issue 
Don't just post a thread here that you want to tell and convince us that having account bank account now is not good or investing in the bank are in a big risk this time.

that's true, banks don't usually do that without any valid reason, maybe you violate some rules and regulations of the said bank. But their's some instances that the bank can terminate or close an account without further notice. example their client open an a checking account, i think there is a rules that once you issued a check that is name by you and was bouncing check, first offence your account will be charge and if you don't fixed it they will closed your account without any further notice or letter coming from them. correct me if im wrong thank you.
Don't worry banks would not do anything against the law because the punishment is very serious for them, and also they will be penalized financially.
