Who can help a consumer who has been ripped off and taken advandage of by a big company? Nissan of Union City took my down payment on a vehicle that they did not have the title to sale. I returned the car,however the general manager refuses to refund my money. The contrct says that if finance was cancelled the customer will receive a full refund per . But after 14 months they still refuse and have verbally/physcially threatened me.
