Best medical lab in Allen, Texas (TX) 2025

I had an appointment on 3/31 at 4:40pm yesterday to get blood drawn. I received a text message that said to check in by clicking the link when I arrived. Once I checked in, it gave me an option to wait in my car or inside the lobby and I would receive a text message when it was my turn. I chose to go in and wait until I received the text message. There are 4 chairs in front of the door (see photos). I looked inside the window several times making eye contact with a lady inside. She never acknowledged me so I assumed she was a patient. I often got up and looked inside. Just figured they were running behind. 1 hour later she and another lady walked out the door and I said I have an appointment. She said we are closed. I said but I had an appt at 4:40pm. She said no you don't have one and you should have come inside if you had an appt. I mentioned the text I received and she said I was lying. She also stated I was sitting at the wrong place and those were pharmacy chairs. She said people often get those confused and that she saw me out there. Both ladies were telling me it was my fault, never apologized, refused to help me and could care less about the situation. If they know people get confused, why wouldn't she come out and check periodically?! Why send a text saying to wait for another text??? The lack of empathy and rude behavior was beyond anything I've ever seen from a health care provider. I guess they don't care about their patients or bringing in business. They continued to argue with me as they walked out. I truly believe they knew I was out there and supposed to be seen but I was the JOKE of the day! JUST WOW! Don't waist your time with this place. I've attached a picture of wear I was sitting right next to the door for reference. I"m giving this 1 star because it will not let me post but they get ZERO from me. ~kelly
