DO NOT BOOK.
I booked one month in advance for a facial that I purchased with a Groupon voucher. Two days before my booking I received a call saying that 'unforeseen circumstances' had arisen and they could no longer accommodate my booking. The unforeseen circumstance was a beauty expo in Sydney that I googled - it had been planned 3 months in advance. When I enquired about changing the day they couldn't get me into another appointment for months - after which point my voucher would have expired. I politely contacted them via email to request a refund and they replied in the most condescending way possible, insinuating that I was a child and trying to argue that a beauty expo is an 'unforeseen circumstance'.
I am not usually a complainer - I completely understand that things change and ACTUAL unforeseen circumstances arise, but I am so furious with the way I was treated in this circumstance that I want to warn other people not to book - or at least to be very wary when booking with this clinic.

Approximate cost: $75
