Dentist and reception give disgusting service

My wife booked an appointment for cleaning her teeth, while she explain to the dentist she is their for cleaning the dentist told her she don't have time to do it now my wife must come back, then my wife asked the dentist if she can then do all filling in her mouth but the dentist was in a rush and only filled two spots and told her to come back again, furthermore when I made the appointment I asked the receptionist if there's going to be any additional fee to be paid and she checked the medical aid and told me No the medical cover the appointment and I asked her again to confirm, in addition when my wife was done with the horrible experience the dentist gave her, the reception gives me a statement that I have to settle. This is horrible service from Intercare to mislead us and to make us come back for the first reason of appointment.
