I have no issues with the service, I think the technician has always down a great job. My only issue is with the booking service. Scheduling an appointment has been more difficult due to the number of Groupons purchased which is understandable.
When I first purchased the Groupon last year, I would look on the online booking system to see what times were available and try to book my appointment via e-mail. Apparently there is a glitch on the website, because it doesn't reflect available times. In order to contact them, you press 3 to speak a person. The phone system is also very misleading, because it states that if you are a new client to press 3. What it doesn't tell you is that anyone can press 3 to speak to a live person.
The final straw for me was when they cancelled my appointment (Dec 20th), which I'm totally cool with. I'm just not cool with how it was handled. When it was cancelled the voicemail stated that she would call back to make an appointment. I e-mailed the next day, and they suggested I call after January 2nd. I called after the holidays and it was busy. I didn't bother leaving a message, because at this point I am just so frustrated, and sent another e-mail. They were not available that date and suggested that I call in again. I then get a reminder call on the Saturday notifying me that I have an appointment on Monday. Mind you, I haven't spoken to anyone in ages. How do I have an appointment in January that I am not even available for?
My suggestion is save your time, money, frustration and just don't bother buying the Groupon. Personally, it doesn't seem as if they have the resources to handle the overwhelming number of Groupons purchased. If you choose to buy it, good luck playing phone tag and sending a copious number of e-mails throughout the year.
