Mahindra after service - non existing

I must say I am very happy with my kar. Stunning ..everything that I want. KUV100 8. BUT the after service is non existing. Nobody told me my car need to be service every 6 month. Why every 6 months? ... .Nobody knows. I take my car to Centurion Service centre. They do not check if the spare wheel is there or anything like that. She print out a form I signed and give the keys. Two hours later they phone and say the car is ready for pick up. I work until 4H30 could only pick it up then. When I arrive my car is parked outside, they just give me the invoice and key and is very busy packing up to close. When I arrive at home a check the spare wheel sho! it there ..what a relief! BUT my vehicle's engine was not washed at all and there is no sign that anything was even changed or touched, no finger marks ..the dirt just sitting there as before, but the invoice is for R1300 and according to that part where replaced etcetera. It felt like I just took the car there to be washed , and the wash was not even done properly, there is a big scratch in the inside of the drivers side door and someone moved the vehicles shoes was dirty and all the prints left there. I have no good feeling about the service and cannot go back and forth. I work full day and the garage is far from where I stay and work. Is is already a schlep to take the car every 6 month and that for nothing but frustration.
