United StatesI had questions about charges on a bill with Quest Diagnostics. The customer service representative here in Houston was Kevis C. I can truly say that this gentleman gave me the most thorough, pleasant and patient service that I have experienced in years, honestly. Rather than going over the top with the superlatives I will say in closing, that whenever I call any organization with a problem, I hope (a) Kevis C. is taking my call...
United StatesQuest is a bunch of scammers. My bill was paid in full in August 2025. In September they started harassing me with the claims that bill was not paid, and now transferred it to collection. They ignore my messages and there is nobody there to speak with. Pure scam.
United StatesThere is no customer service. Everything is AI. You will not get a question answered. You will not get any help or support. The space was in disarray and dirty as well. Avoid this place at all costs.
United StatesIf I could give this company a -5 star I would. The whole process sucks, from the app- setting it up and it taking so many steps to verify identity. It is so dumb and ridiculous! The test results take dayyyys to complete, i’ve been waiting and waiting and still nothing! No customer service provided. Even went to the lab to check because there was no way to contact them. I’d rather pay a bit to do it at my doctor’s lab than dealing with this again. Do not recommend!
