I bought a Groupon but when I called to book an appointment, they told me they could take me at a particular time without hesitancy. They then asked how I heard about them to which I responded I had a Groupon, and I was subsequently told that they actually had no appointments for me and I would need to wait 2 weeks for the "Groupon Specialist". There is nothing in the fine print or coupon indicating this and I think it's a terrible customer experience.
