Toyota Barloworld Centurion Pathetic Service!

We took our car for service on the 28th of May for service and we were told that the aircon pipe needs to be replaced. We asked them to go ahead and replace the pipe only to find out they don’t have the pipe on stock. They promised to order the pipe and all us. Until today no one has called us. When I phone Toyota and complain the Manager only said I am sorry there’s nothing I can do now. I can order the pipe and let you know when it is here. My frustration is that I need to drive the car tomorrow for about 10 hours or cancel my trip. I can’t cancel my trip as I am a Small business and if I cancel the trip I cancel my income! All I expected of them is to look for the pipe or refer me to a Toyota that has the pipe but nothing only a sorry.
