Unhappy customer with service

im really not happy with the service received today at BMW Menlyn, my car was the 3rd in the queue and because i m not on their motor plan , even after i have given them details of my Motorhappy details and telephone number they still managed to start with the process at 13h00 in the afternoon and on top of that my service consultant California Khumo Mdluli was only able to get the quote approval at 17h00. And in addition to that there is a part that they do not have in storage she also only found out they dont have at 17h00 because the mechanical/technical person assigned to my car only told her at 13h00 and she cant order the part today. And im told that i will only be getting the car on Wednesday since tomorrow is a public Holiday and the part will only be ordered Wednesday morning. This is so inconveniencing and not acceptable at all.
