I purchased a skin and more groupon for facial and i called her to make an appointment. She did give me an appointment for friday the ** and told me i should send her my groupon so she can process it because customers from Groupon has been calling and cancelling and make a gap in her appointments but i will still have ** days to use it. I texted her my Groupon voucher and went to my appointment and found that her door was closed!! I texted her and she told me my appointment should be for Saturday and I replied that no my appointment was to be friday than she started apologizing saying she had a family emergency and she had to leave!!. She asked me if I wanted to reschedule and i said i will call you back in * minutes, so i did call and she never answered and I texted her as well yesterday and today and she still haven’t replied. I think this is so unprofessional and might be. A scam and i wish for a refund
