Terrible Service

I bought a demo model Mitsubishi ASX GLS from the Vereeniging Branch. The staff was very helpful. I also don't have any problems with the vehicle itself. To make a long story short. The vehicle is now due for it's first service and as I am on leave in Cape Town I thought it well to take my car to the Paarden eiland Dealership as it will go over mileage on my way back to Gauteng without being serviced. I left my car at the dealer knowing that Mitsubishi will provide me with the convenience I deserve after paying so much for a vehicle. Just to be called by the dealer advising me that there was a Vin Mix and that the car cannot be serviced as this need to be sorted first. Apparently the problem is with liquid capital. The dealer forwarded photos but it's 4days now and the problem is still not sorted. I had to phone liquid capital numerous times myself. . I still don't know how this became my problem? As I feel that the problem was supposed to be sorted in the back end and as a client I wasn't even supposed to be inconvenienced by this. My car was supposed to be serviced the day I took it in and whatever problems there was with Auth was supposed to be dealt with in the back end.
