As they havn't given you 60 days notice, then they must suspect you of providing false information, illegal activity or not being entitled to open the account in the first place (I'm assuming you havn't been violent towards any of their staff recently). So they need to tell you why. If they can't then I would accuse them of being in breech of their own terms and conditions and liable to damages for your loss of trade as a result of having your account closed.
Don't let the bastards get away with this.
