New thinking new possibilities. Not happy about your service

I have been using Hyundai Germiston dealership for many years to service my vehicle and I recently purchased another vehicle with them late last year which is a Santa-fe. The brand on its own is very reliable and most of my friends are driving Hyundai because of my recommendation. The service I received today is very pathetic as I dropped my car in at 07:30 and till 15:30 no call received from them and I decided to follow up and I spoke to Herrmine and I wont lie she's very kind however I did not like the fact that I was not contacted all day until I made a follow up and still be tolled that no stock for brake pads. why did they book in the car if they don't have stock because it was specifically booked in for new brake pads. and this triggered to the service I received last year when I bought my Santa-fe they gave me aftermarket carpets for Hyundai i20 to use them on a Santafe because the carpet on a drivers side was thorn and when I return it back asking for the right/correct carpet they don't want to accept it and I have not used it because it cannot be secured properly and that can be very disturbing when I drive imagine a thorn carpet for a car over half a million and drove it less than 4000 km and brakes are worn out already. Their new service consultant Hermine checked on the system and told me that the 125 point check was not done before the car handed over to me. why? come on Hyundai Germiston you are letting me down.
