No sense of urgency at all/ Poor communication !!

I would like to write a complaint about the service i have received from the Mazda at Clear water. I have been taking my car to service at the Mazda in Edenvale since i bought it but because i have moved to the north i decided to take my car to clear water . To begin with i was not even added to the list of people that needed to be dropped of by their driver after dropping the car. After dropping the car at about 07:30 i did not hear anything back from the dealership till i eventually got hold of Tlhogi after several attempts to reach her and being told she was with a client, during my call with her she mentioned in passing that the car would probably be ready at 16:45, that being said i assumed she would give me a call to say the car is now ready round about that time because i could not assume that on my ends, to my suprise she called me at17:15 asking if i was still coming to collect my car!!!like where is the sense in this , all that was required is a call to let me know he car was ready. That being said , it is the first time that my car has slept at a dealership after going on for a service. Despite the fact that the people are very welcoming when you walk into the reception , you will be frustrated by the level of incompetence and laid back attitude!
