LabCorp review: Do not trust online site

I made an appointment online for the Alston Ave, Ft. Worth.
Received a confirmation, drove there and checked in from my car, received another notification that I was checked in and to wait for a text to begin my appt.
Waited 15 minutes in vehicle and decided to go in. Found a note on Lab Corp’s door stating they closed at noon for the day. My appt was set for 1:15.
I met others there that came for an appt, after noon, also.
No notice on Lab Corp’s site while making appt, or when I called and spoke with a rep to check hours, who stated regular hours on New Year’s Eve.
Get it together Lab Corp.
