Worse client service EVER

I had made an appointment to see the dentist at the medical center. Apon my call the receptionist took non of my details for the appointment and was exceptionally rude on the phone .came the day of my Appointment arrived at reception to the same reception with no hallo how can I help nothing ! Told her that I had a 12:30 app with the dentist ....she shrugged a clip Board ato me and told me to sit! So I filled in the forms and handed it back to her and was yet again told to sit! By 1:00 I asked of the Dr world be much longer as I had a tight schedule...was answered "however long the doctor is!" When the back to my seat only to have her yell from her chair...." you can pay so long" so I payed for an appointment that I had not yet had? 1:30 I was told to go the the room on the right where the Dr will see me . Went in only to have to drive tell me she is a GPS and nothing the dentist. She said sorry your appointment must be mixed up and was told to go back to reception to rebook an appointment with the dentist and come back! By this time I was really angry ..went back to reception and told the lady that my appointment has been mixed up and that I need to see the dentist and not the GP? They both stood starring at me ? No apologies...no rebooking so I demanded a refund and left! I have never received such bad client service in my life! I am also in the client service industry and know how it should be DONE! I will never go back there and wouldn't recommend it to anyone! Disgusting!!!
