My first few experiences with Simplicity were less than stellar, but they have made some internal changes lately and seem to be getting things back in line with where a company of their size should be as far as customer service and organization.
I bought my first Simplicity package through Groupon (underarms) and had to wait over 2 months for my first appointment. I also had an experience where I showed up for my 8am appointment and no one was there... no staff at all. When I called the main number they said that the one girl that was scheduled to be there called in sick. Needless to say, I was pretty upset (I got myself out of bed at 7am just for that one appointment and didn't get a call... AND they weren't able to get me in for 2 weeks after that appointment that they cancelled on me). Also, was frustrated that the Chandler location switched locations THREE TIMES in less than a year.
But, after talking to a manager, it seems that they oversold their Groupons and were not prepared for that many customers at once (duh) and they had some pretty big issues with the locations in Chandler that caused them to move.
Anywho, lately, I've had no issues. The gals at the Chandler location have been very nice and friendly, making me feel comfortable every time I'm there.
