"While the website said I had an appointment... And the staff at the collection center was very nice... Your collection centers are setup to fail. You don't do appointments right."

"Got Covid test. Told 2-4 days for results... Well it will be a week in a few hours and NO WORD! What's worse is there is NO CONTACT NUMBER, no way to call, nothing!!!"
