If you know who it is, why are you here on a site for looking up unknown numbers? Just because it was legit for YOU does not mean it will be legit for OTHERS
Hey "Kristin". Here is what happens when my doctor calls me to remind me of an appointment. "This call is for (my name), this (my doctor's name) calling to remind (my name) of an appointment on xxx (day of appointment) at yyy ( time of appointment). If you want to confirm this appointment press 1, if you want to cancel this appointment press 2.
Now in what universe would it be necessary for anyone, including yourself to take the time to look up the number after hearing all of that, knowing that you have an appointment, knowing who called and why, just to announce to the world that you received a call from your doctor. Please, I hope you come back to tell us, but I certainly don't think you will.
