I bought a Groupon here for laser hair removal within a six month time period. It's been five months now and I've only been able to use one session because it is literally impossible to reach this company over the phone. They have not once answered the phone, their voicemail is always full and they never call you back.
Like other posters I got the "our machine is broken" cancellation, with no follow up to reschedule and they never returned my phone calls. At this point I am almost positive they do this on purpose to Groupon customers to try to con money out of them.
The one session I attended started 25 mins late. There was no receptionist, just an empty desk, and when the technician finally came out 20 mins later she simply stared at me and didn't greet me or say anything. I literally had to go bug her at the desk to get my appointment started. It was very strange and awkward.
I've asked Groupon for a refund which is currently pending.
