The billing services for Sonora Quest are the worst ever. They seem unable to just look up my account. I paid online but obviously it was somehow not recorded. I call the billing number listed and they want some type of number that I do not have but the pre-recorded voice does not allow me to get assistance. Then I finally get through to a line and they are closed from noon to 1p. DO YOU WANT MY FREAKING MONEY OR NOT???? WHAT A JOKE. NOT GOING BACK just because of the hassle factor. The phlebotomists and service at the centers are great, but obviously the billing department leadership does not have a clue.
