McCarthy Toyota Gezina (Car Service)

I had an appointment with Toyota Gezina Pretoria Branch on Saturday Morning at 8am My partner went there on my behalf. they needed to replace breaks and new battery, he was there the whole day ,later on he was told that they can not assist him because the breaks needs a disc it goes together, and the shop for battery its closed hence the car went for a service on the 8th Feb, my question is why didn't they mention all things at once that needs to be replaced, why are they only mentioning disc after. If this things goes together why didn't they pick it up when they where servicing my Car same day,was my car really went for service or what? I agreed to replace a Battery, but they only told him that they must make order for battery its not there hence they knew we need a battery replacement, we booked this appointment on time. this is very bad service, I feel very bad not being treated fairly, that was our time but it seems like they dont care, or do you put small car behind like my car Aygo and attend to big machine (Big important cars)1st, well for your information small or big car its the same name Toyota and should be treated equally,why did Toyota have Aygo on sales if its going to be like that when it come to service. I did not ***** this car I bought it from your dealership and thought serving it there will be fine and It deserve good service also,why did you waste our time not taking us seriously.I dont appreciate this at all, I will go to Toyota Hatfield maybe the service will be better , no more car service for Toyota Gezina, you dont take your customer seriously or me rather, you think coming there was a joke or we are bored,you are not reliable , the only Service I got which is perfect and I will always appreciated is when I bought my Car ,other than that NEVER. EVER go to Gezina for service again
