Account banned for no reason

My son's account just got banned for no reason. The account was just set up and within a day or 2 it was banned. The account was never linked to anything and never used it besides setting it up. It was stated for violating the terms and conditions but won't state the actual reason. This is absolutely crap to be doing this to your customers. This why EA has widely become known as one of the worst companies to exist and your customer service is hot garbage. Can someone please explain to me why it was banned, as in what the exact specific reason or thing it supposedly violated to be banned, not an generic violated terms and conditions which means absolutely nothing.
