OP's situation is different and he needs to contact US ASAP in order to figure out what's up. If he's been engaged in shenanigans with any of the accounts, as his post suggests he may have been, the accounts may have been frozen pending an audit and eventual closing if fraud is determined.
As to the tickets, if the account is closed out for fraud, US will either cancel the tickets or show an add/collect for the amount due if the miles are invalid. At some point, I would expect US to simply cancel them.
So, back to square one. Call, call & call. Ducking the call ain't gonna get this fixed if it's fixable and if it's not fixable, better to find out now.
