Oh man, I know you don't need this kind of uncertainty, getting yourself all psyched up for an appointment and then feeling let down

Try ringing through again in the morning to double check, perhaps the receptionist had it wrong -- or, perhaps he has a good reason for taking the extra time off, lke a family emergency? With the new year and everything maybe no one had got around to contacting you yet... He/they really should be more organised, but try to hold off on any ranting 'til you know what's happening and why, might be an innocent explanation. (Did that sound grown up and sensible? I'm trying! )
