I like to keep records of everything I spend, so I was planning on asking them for an invoice for my procedure, but they gave me one before I even had to ask. I was impressed with their professionalism. I don't think I have ever been put on hold here for a long time and am so impressed with how quickly all of my questions are answered. There's nothing worse than having to wait on hold for a half an hour just to get someone to talk to you. They were so easy to reach in an emergency, they answered my call immediately. It is a relief to know that I can count on them to always be there for me when I need them the most.
