question about engagment shoot

i called my photog today to set up the appt. and asked when my photog that would be doing our wedding is available for our e-shoot. the girl who answered the phone is like they're (the photogs) shooting weddings so ur e-shoot will be w/someone else. i was like i thought the whole point of an e-shoot is for my fh and i to meet with and get comfortable with our photog. shes like no either myself or so and so will be doing it. lets just say she had a tone to her voice too. so i said can u have so and so (the woman who i booked with) call me back please. she said sure, i'll do that.
so am i wrong in thinking that the e-shoot is done by our wedding photog.?

ETA: ok i just spoke with owner and explained that we are out of towners so it would be hard to make 2 trips (1 for the e-shoot and then another one to meet the photog). he said sure no problem and was even able to get me and FH in on a saturday in April. so much for the girl telling the weding photog's aren't available. so FH and i have our e-shoot with our WEDDING photog on 4/21. YAY!!!
