O'Reilly's Auto Parts Poor customer service and extremely rude treatment Elgin, Texas

I had a problem at an O'Reilly Auto Parts honoring its receipt. An O'Reilly employee a short while ago told me that the store takes back parts even if they have been opened and used. I should have no problem returning it as long as I kept the receipt. He raved on and on on how this is a "great mirror" and I didn't need to buy an expensive one. I brought the mirror to test it, it didn't worked out for me, so I brought it, the packaging, and reciept back to a local O'Reilly Auto Parts within the month.

Right off the bat after I brought in my product and asked for a refund, a male associate by the name of Travis rudely stated to me, "It's opened and it can't be taken back." I pointed out that I brought back the part, packaging, and receipt and the associate from the week before stated it was a great product and it clearly is not.

To note, I got help installing the mirror by several people and it still didn't work out due to it's glare and weird angle distortion and it just being an inferior product. A non-O'Reilly auto associate told me straight out that the mirror I brought was inferior and he told me that he puzzled on why any store would even carry this product. "That associate should have sold you a mirror based on your car and not something cheap like this. It just doesn't work." I brought  another mirror from this particular dealership and I have no problems with my new mirror.

I asked to speak to the O'Reilly associate's manager, and he stated that the manager wasn't in. I asked if I could get the manager's name and when she would be in. The associate rolled his eyes and swore under his breath very loud for me to hear, "God d**nit". I told him he didn't need to be rude to me. He told me that I wasn't listening, and I told him that he wasn't listening to my question on why it was so hard for him to give me his manager's name. I was also told that a receipt doesn't guarantee anything by him. He was basically ranting and raising his voice to me. I was just dumbfounded, not just because of the crude treatment, but also because a store didn't honor its receipt.

I don't understand what I did to deserve such outright rude, unprofessional customer service. I'm still not sure what to think of it. I would rate an "F" minus for customer service and professionalism with this location.
