O'Reilly Auto Parts

Went to O'Reilly today (8/30/21) to check on some brake parts. Asked if there were any rebates on brake parts, was told that there was a 20% rebate on pads/rotor combination. Sounded good, so bought 4 rotors and pads for my car (counter 593351, invoice [protected]). I utilized the Military Discount. After paying for my order, I asked the sales clerk if she gave me the Military Discount... she said yes. I also asked if she included the 20% brake rebate... she said yes. Only after repairing my car did I notice that I had only the Military Discount on my invoice. I went back to the store and waited to speak to her. Another clerk asked if he could help me. I explained the situation. He said that the rebate on the brake parts negates the Military Discount, and that I was given a 10% brake rebate. I explained what I was told at the time of sale, he just blew it off and just stared at me. I told him that the reason I had bought more than I intended, was because of the 20% offer. Again he just stared. He never asked the clerk who waited on me anything, even though she was stranding feet away. I told him he had just created a unhappy customer, and that I was leaving unsatisfied.
