Unacceptable response on Faulty new Vitara Breeza..

I bought a new Breeza at Produkta Motor Group Nelspruit last December. In less than 24 hours I noticed that the key keeps jamming and wouldn't come out of ignition. I initially thought there is something I might have done. This kept happening when I was at home for holidays. I reported and dropped it as soon as I was back. Unfortunately, the key work out fine once I get to the workshop. It was the most strenuous period of my life, but they would refuse to do anything as they claimed they did not see anything. This was regardless my explanation that it was inconveniencing me, humiliating and affecting my health- I had anxiety for the entire period every time I got to the car. The key would sometimes eventually come out after I do several forward and backwards or sometimes it would take me driving around few kilometers. Most of the times it would happen when I was about to go to the shop and would end up not going or had to go home and fetch my husband so that he could remain behind on the car. We (as my husband was also involved) were insulted and humiliated by the car dealership and the workshop, even the head of the dealership. I reported to SUZUKI customer service through email, but I was completely ignored- not even an email promising to come back to me. I even explained that this was my second car with them, they were not bothered by my loyalty. We even went to the extent of begging the dealership to keep and drive the car for a week so that when they experience the problem. They continued insulting me. One day I was at work and the maneuvers would just not work as a result I missed a meeting as I could not leave the car with the key. Luckily when I got to the workshop the problem was still on. It was only then that they replaced the faulty party- 3 months of agony for me. Since the day I picked up the car (which was 50 days ago) I never got even a relationship centre email checking if the car is working well. The head of the dealership never responded to any of my emails- completely ignored me (In face undermined me). I have copies of all emails and also the screengrab from Tracker as it shows all the time when the key jammed, as it would record a I bought a FAULTY car, and the dealership is not bothered. I do not feel that my car is new at all. There was not even an apology from them, including the head office. I doubt they would treat ALL customers this way.,
