Kia Menlyn and N4 Autocraft

I went to fetch my car on Saturday after arranging with N4 Autocraft to let Kia Menlyn that i will fetch the car. When i got to the workshop it is closed and only to find that the person I was told to fetch the car from is not at work and nobody else can assist me including the Manager. My car is standing in the sun and will probably have to withstand the storm coming this weekend. No one can give me the key to my car as they are apparently locked up. Terrible service from both N4 Autocraft and Kia Menlyn.
