I'd just play phone tag with him for a few days until my sister found me on campus.
i.e. Make sure I'm not home when he calls and turn off the answering feature on my machine.
He really couldn't do anything about it, especially since it's my play money. Regardless I'm in the clear, but the less fake grief I have to go through in dealing with my rents, the better.
