I have never received a service from this place, fortunately or unfortunately, I dont know.
When I find specials on Groupon I always like to call the company before purchasing, and pay the companies directly, because I know Groupon takes a big portion of the money. In my case I'm especially glad I didn't purchase Groupon. I have called this place so many times and have never actually spoken to someone or received a return call. That's just bad for business.
It's been a few months now, so hopefully they've gotten better about calls.
