LabCorp review: Unprofessional staff and they moved

The first time that I went I had problems with the staff at the Lomita location. They were very unprofessional. The woman acted like she needed some Prozac. Had to wait hours. I decided to try a different location in Carson on Avalon. They were worse than the Lomita location. I went back a second time to the one on Carson and found out that they had hired all new staff. It was a little better. Even though I had an appointment it was still a long wait. Today after fasting I had a 10 o'clock appointment with the Carson one on Avalon. They were not there. The door was locked. I went into the other office and the woman told me that they had moved. I did not get any kind of notice informing me that they had moved. THIS IS UNACCEPTABLE! SHAME ON THEM! I do not want to go back -- I no longer trust them.
