Town Center Nissan

Please dont do buisness with Town Center Nissan I have been a buyer twice and was told each time that if I referred someone I would receive a referral fee. I have refered 7 buyers in the last year and a half to the same salesman his name is AZIZ. I have spoke to him many times and each time I am told the checks will be coming. They have not, not one. I cant speak for other Towncenter Nissan buisness practices but if they fail in this area so terribly I would suspect other poor buisness practices.
