Bad After Care Service

On the 15 January I took my vehicle in for its 30 000km service and advised them that there was a problem with my vehicle which I asked them to check. I was told when I collected my vehicle that the top shocks had gone and that it was a warranty replacement that had to be done. They said that warranty claims were done separately and that they would phone me to let me know when I should bring my vehicle in. on the 16th of February I still had not heard anything so I phoned to find out what was going on only to be told that they had internal problems, the person who was doing the warranty no longer worked there. A week went by and still heard nothing so I phoned only to be told that I had to take the vehicle in for photos to load the claim, which was done. A week later I phoned again only to be told that they were waiting to see if the claim had been accepted and if so, the parts will be ordered. By now I am fed up and am receiving no joy in this regards, I now no longer want to drive this vehicle as I am not sure whether it is safe to do so or whether I am causing more damage by driving it.
