Bad attitude and lack of customer service

There are certain customer service skills that every employee must master if they are forward-facing with customers. Clearly perfect 10 crescent owner has no clue what this means because she has failed to discipline Grace, her staff when I Reported to her that she has been rude to me. Incident: I made an appointment and the receptionist told me to come in at 11:45 when I get there I'm told my app was at 11:30, 2ndly I ask her to fix a nail that I thought was *****ed, she replies n says she can't I must do it myself next thing she leaves me right in the middle of a service, tells me I was late for my appointment meanwhile they gave me that time and starts another client whom I assumed has more priority than me. I am a regular client at perfect 10 crescent I will not tolerate being treated like this hence I will never set foot at any perfect 10 as there are many other competitors who are willing to provide a perfect service. I just could not believe that the owner did not even apologise for this but instead took the employees side. I'm totally devasted by the owners actions more than anything. She too needs to learn more on customer service.
