Nissan Atlantis poor service

No star. Very terrible service from the sales person. The sales person did not want to listen to valid complaints within 24 hours of a used VW car purchased cash. The sales person rep**** by saying that I am coming back to him with petty issues. This is the attitude which I get within 24 hours of a cash purchase. Yet the issue is not petty but big. Even if it was petty you have no right to address a client in that manner.
