I tried a number of times to book and they were never ever available. I understand they put a special on groupon and living social at the same time so they are busy but certainly not every moment of every day is booked. I toyed with the idea of booking without saying it was from groupon to see if anything magically opened up. What also is a major red flag is that they refuse to make an appointment without getting the groupon voucher information up front. Nobody has ever done that. How do i know they won't claim it as used when I haven't gone yet because they refuse to give me an appointment. They want the groupon money without giving the services. I have been trying for weeks (seriously, weeks!) for an appointment and nothing yet is open. I got a refund and used it for Glo up the street and they are AMAZING. The owner is so sweet and the new person (why they did a groupon) has tons of openings. Clearly Harmony is going for a cash grab.
