Autozone

I went into the store to replace the brake pads on my 2010 Nissan Maxima. I was uncertain if I had purchased front or rear brakes from Autozone. I told the associate that I would need new pads and that I believe that the front ones should be under warranty. After looking at my account, he was unable to find where I had purchased front pads. He retrieved a box from the shelf to verify that he was looking at the correct product. So at this point, my question was answered to my satisfaction, I had not purchased any front pads.
At this point, I asked the associate to in fact verify that I had purchased rear pads. He said that he would not check because my front pads were not under warranty. I told him that I understand that, I just want to ensure that my purchase of the rear pads were on file. The associate became rude and agitated and said «WHY!, You don’t have the front pads under warranty». I explained my position again and he rudely stated ‘I didn’t see ANY brakes for your vehicle”. I then requested he look again while I watch. he replied rudely, «I will only do this ONE MORE TIME». As he pulled up my car’s history, there were about four items present. I asked him to look up the part numbers, and the first one was a brake rotor. At that point I said «that looks to me like I did in fact purchase brakes for my vehicle». He then threw his hands up in the air and «said someone else help this person, I’m done with him». Now, I am angry as he was and said «You shouldn’t be such an idiot» as a female associate came to help me. She in fact verified that I had purchased the rear pads. I thanked the female associate, still angry I said «Thank you for not being an idiot» –Inappropriate I do admit. That’s when things got worse. The associate started shouting «F*CK You» repeatedly behind the counter as I stood there surprised by his actions. Then, it gets better; another male associate comes from behind the counter, gets in my face and says «Who the F*CK do you think you are? We will F*ck you up in here!!!» The female associate who was helping me had to come and restrain the guy as he repeatedly shouted «I will F*ck you up!!!» .
I totally couldn’t believe this happened. I’ve since notified their district and regional managers and await a response.
