Quest Diagnostics review: Customer service

June 25th I had an appointment with quest at
8191 Timberlake Way Sacramento, CA 95823 at 8:45am.
I logged in at 8:40am and waited to be called. I seen that my name disappeared and thought I would be called next. Two people who came after me were called and as I stood there to talk to someone, no one was at the front desk and other people had questions as well. The workers saw us needing help and did not help. When I finally got someone's attention, all they said was they would call me soon. I waited another 5 mins and someone else was called before me. I do not appreciate this quest at all and I've been to multiple different quest, this is the worse one! I will not ever be coming to this quest.

Desired outcome: angry
