If I could give them a negative star I would. I had to use their service for COVID testing for international travel. I was required to use them by my government agency. The agency would cover the cost. When it came time for me to file my expenses I could not because I didn't have a receipt. When I contact them for a receipt they told me I owed $50 above the agreed cost. I was escalated to a person that said they corrected everything and billed me the correct amount and would send me the receipt via email. I waited and waited and no receipt. I had to file the expense without a receipt. 3 days later I received a bill with the charge $50 above. I called them twice and got their foreign call center who apparently didn't know how to use a hold button or just simply hung up on me. Needless to say, this company either doesn't care about their customers/patients or are simply incompetent. Why anyone would trust their medical business with this company is beyond me. Stay away. Don't waste your time with them!
