Bad Service

I purchased a Nissan Micra in October 2012 which was a demo in Nissan Eastern Cape, Uitenhage because Nissan SA transferred me to them. After receiving the vehicle I experienced some difficulty with some gears. The problem after several times taking it to the nearby Nissan was not sorted because they said they do not have a machine to evaluate the problem and that I will need to give them the vehicle so that they can take it to East London. That will have to leave me without a vehicle so I requested them to supply me with a courtesy because it was not my fault and they refused. <br> I am afraid that the problem still persists and the Warranty is coming to an end without being assisted which will now become my problem if it comes to that. I tried contacting the salesman and informed him of the situation but He never got back to me eversince. I request that Nissan takes the vehicle and provide me with a courtesy car as none of this is my fault and I need to have a car to use. I cannot tolerate this because it seems as if I am paying for some damaged goods and I am still under Warranty but my request is not being taken seriously.
