Bad service

My husband bought me a Datsun Go in Desember 2014. There was some small problems, the hydraulic shock at the boot did not work right, the sunwiser broke. They fix it all after my car stand by them for 3 to 5 days. My car went in for it first service end July 2015. Sins then my car went back for several problems, radiator broke the gearbox had to be replaced.When I got my car back after a month the windscreen was cracked. The inside was so dirty it looks like they took the oily pars apart inside my car. They said they will fix it. After a week I still have not got my car back. I am really not happy with the service and the car anymore. Will not recommend Nissan Vereeniging to anyone.
