Sorry you guys, I have no idea what's going on, but let me check this one out a bit further. Two things could be the problem. Either 1. the number could have changed( I really doubt this by the way) or 2. they could be screening the phone for L.E. You know what you can do is maybe tell them before they say anything that you'd like to schedule an appointment. This way you give them a chance to automatically assume that you've been there before.
