Peugeot Westvaal Menlyn - Horrible service

My mom took in my Peugeot for it's first service this morning at Menlyn's Peugeot Westvaal (newly opened by the way in January). Around 10am she received a call to say the car was ready and they will pick her up to fetch it at 11am. When she got there, the car was not ready, still dirty as well. She was told it will take another hour to have the car ready. Mind you, she left work because they said it was ready and now they expect her to wait another hour while they finish up. What an inconsiderate act. Mom asked for the invoice/document outlining what they did during the service, they said they can't give it and they will email it, still no email received. As the owner, I called them to complain and without listening, the reception lady forwarded me to the service department. Very rude. The service department said I should be talking to their manager who is not there and I should call later. So basically no one wanted to listen, What kind of place is this that I complain and I must call when it's convenient for people and no one is trying to address my issues? Not even an acting manager available to assist? This is disgusting customer service. I have never been treated this way in my years of having a Peugeot vehicle.
