Suspending account

I opened an account for my son in December and a month later the amount is suspended because I must supply proof of adress an id document, when I opened the amount I had these documents and copies where made, why must I take time to go and sit in a que and with a consultant a month later to provide documents I already gave and now the account is suspended for that, when I go in it will be to close the account not to provide documents, and to think I wanted to open my own account because of the good service I received when I opened my son's account
