Toyota of Hackensack

I am dealing with 4 different TOYOTA dealers in Northern NJ and this one is the worst ever I experienced. I know all the dealerships are expensive anyway so that they should treat customer as royal as any other service especially where purchase was made. But, this dealer is really different, they tried to make me down in many ways, not only their attitude but also treatment, especially which was my case for the repair of TSB issue as TOYOTA already notified all the dealership. So, it should be no argument with customer for replacement the parts. But, they argued in the beginning when I show them a copy of TSB I printed out, then after 2 hours diagnosis, they admitted there was A TSB issued by TOYOTA and need to replacement which supposed to be, so they promised to order the parts, then 2 weeks after, they called me and finally declined my service because I complained TOYOTA HQ for their treatment. Can you believe this non-sense? They do not serve customer in the name of TOYOTA at all. They even hung up on me in the middle of the conversation. By the way, afterwhile, I went to another dealer for the same repair and it was so smooth and got repaired without any question they asked. Be carefull!
