Asking whether a signed contract has been received

— Arthur, did we receive the signed contract from the talent agency yet?
— No, apparently Keith wants to make a few last-minute changes based on his client's wishes.
— Well, that's news to me. I was expecting to have received the fax from him by this morning.
— I know. I've been trying to reach him by phone but he's not picking up. Shall I try to contact the office manager?
