Lexus review: Denying me service (olatunbosun gbolade)

I took my lexus to this dealership and I was not satisfied with the service provided and I expressed my displeasure about my experience and the service manager WES BOLES banned me from bringing my car for service at this dealership because of my complaints. I sent a complaint to the guest lexus programme and they told me the dealership has the right to deny me service. My intent is for this complaint to get to the headquarters in Japan . I do not know if this would go to lexus guest services in the united states as they were of no help. I live in Oklahoma city there is only one dealership in Oklahoma city . If I buy a lexus in Oklahoma city were do I service my car if I have been banned by the service manager?If I have a warranty do I have to drive to another city to get my car fixed? I think this service manager has exceeded his powers. I think the reason he is doing this is because I am a foreigner and he thinks I am beneath him . I would urge the head office to correct this as this man is denying me the opportunity to buy the car I want
