Quest Diagnostics Corporate Headquarters 500 Plaza Drive, Secaucus, NJ 07094

"Horrible experience. They use monopoly power in my area to give completely useless customer service. I made an appointment..confirmed via email then when I showed up they closed early 20 min before my appointment time. I'm standing outside wondering why the door is locked. Called them ...getting a human is almost impossible. The sign on the door had their hours they were supposed to be open. They send me an text 30 min after my appointment time saying sorry we had to cancel your appointment. A little too late"

"Don't use Quest. Use LabCorp or another vendor. Ask around. It won't take long for you to find a horrific experience at Quest from someone you know. Quest should be investigated for how poorly they treat customers."

"I'm a guest from California, and I couldn't find any place to file a complaint on your website. I had no choice but to leave a message on Google for your headquarters. If you don't welcome walk-ins, then you shouldn't offer a walk-in option. My wife checked in at 4 PM and waited until 5 PM, only to be told that there were no spots available today. How would you feel if you were in this situation? Even ordinary restaurants wouldn't treat their customers this way. Despite having an advanced reservation and management system, you can't disrespect people, especially patients."

"Quest offers poor customer service to its professional customers as well. As a medical professional I am appalled by this lack of service. Calls are placed on hold for long periods, the operators are not knowledgeable, and when transfered the representative say I can't do anything to help. When you ask for a supervisor they don't even have the courtesy to return your call. Quest is a fortune 500 company with a monopoly on certain insurance carriers. They would be out of business otherwise. Given a choice I would not refer my clients to this lab. Beware you are setting you company up for the emerging market to replace you with a more customer focused laboratory."

"This office was absolutely no help. I have received multiple calls from their office asking me to verify my insurance. I tried calling the call back number, and it goes to a concierge service in California. They concierge service does not answer the phone. I tried calling the number I was given, and I got to the corporate headquarters. I got to talk to a human, and instead of helping me, he transfers me to the concierge service. I even told him the concierge service did not answer. All in all, this company has very poor customer service."
