Since we didn't see The Miz's father backstage with Miz and Shane does that mean that Miz's dad has left?

Corey Graves said that we didn't see Miz's dad backstage with Shane and Miz that's because he is on the next flight out of here and changed his phone number so Miz wouldn't call him anymore.

No, Corey Graves was just saying what he was scripted to say. Moreover, Miz' Dad was probably backstage talking to Vince and Triple H.

Not Really. He actually his dad every single week. They'd take care of their grandchild as well.
