40 minutes of waiting at perfect 10

I arrived to the store at 9h00 in time for my appointment asked to have a seat as Sne, my the******, was running late. At 9h10 the receptionist was asked to call Sne - it was only at this point it seemed as though Sne was alerted she even had a 9h00 appointment. She stated that she would arrive in the next 10 minutes- which she did not. It is always made known that you need to arrive 10 minutes prior to your booking and should you not they have the right to shorten your treatment time or cancel, however when it is the company that has left you waiting for over 30 minutes with everyone trying to hide in the back and avoid giving you any feedback it goes by completely unnoticed. The ladies present chose to avoid me and stay in the back of the store instead of asking me if I would like to sit for a hand massage or be given anything to drink. The staff do not even greet or have any sense of pride. The level of professionalism is absolutely poor at the store over all. The fact that staff can arrive more than 30 minutes late to work and not even be questioned or apologise for it is absolutely poor work ethic. How is there no manager on site checking this.
