AutoZone review: rude and disrespect to customer

The worst experience I ever have. Today, we went there to buy the head light for my car. We asked the sellers that we wanted a set of 2009 Honda accord head light when we purchased it we asked the seller to make sure it is the right one I buy. When I went home and tried to inserted the head light to my car, I realized the seller gave me the high light. Then we went back to the auto zone and asked them. The sellers were rude and don't respect us maybe because we are Chinese. We asked why the head light didn't fits our car, then they questioning us we wanted lower light or high light. Before they took me the light, they don't even ask we want lower light or high light. Their response were we may gave the wrong information that was why they got me the wrong light. Are they kidding me or they are the first day of work.? Why they did not ask  we want high light or lower light, then why the seller go inside of the counter and took us this head light? If they bring us the light, we certain think that is the right one for our car. If i took the light by myself, then that was my fault, but if you gave me the right, then it must your fault. The sellers keep saying that is our fault. One thing I can't endure is one of the seller came to ask do we remembered him. We don't know who he is. Then he said, my friend said he want high light and he told my friend don't lie. What is he tried to do. That is okay don't allow us to exchange the item since we opened it. They don't necessary to framed my friend and saying he is liar. We really got pissed off. They are saying that is not their fault that is our fault. How can be our fault?.. You took us the light behind the counter and gave to us. If you need more information of the car, you can just simply ask, we will tell you. Moreover, we never said we want high light and why the seller said we say that, and why he told us don't liar.? What is his purpose? They waste us more than $50  to get the wrong light. We have spend more than $ 60 to buy another pair of head light. The worst experience and service  I ever have in my life.  what is our consumer right? I will not go to auto zone buy stuff any more.
