Mavis Discount Tire review: Tire ordering/installation

I ordered 2 tires for my Audi, and had an appointment for Saturday. When I got to the store I found out that they had only ordered 1 tire. Not only were they rude about they acted like I was the problem. This was my second trip... the tire was supposed to be put in on Tuesday. I have a high pressure job in Birmingham and cannot just drop everything to go to Mavis tire, so after work I drove to Mavis and arrived around 5:25 to have it installed. When I walked in the employee at the desk acted like I had grown 3 arms out of my forehead when I suggested that they put the tire on. He was incredibly rude and made comments like "Do people walk in your place of business before you close up?" My response is you are still open with plenty of time to put the tire on. I said this was your mistake, and I'd like to get my tire on as this is my 3rd trip here. He refused and said why didn't I just come during the day (It's still during the day), and I said I have a job, he said, so does he, right but you're refusing to do yours. My final words were look, its not like I showed up out of nowhere, and his response was "that's exactly what you did" There was no sense of them fixing their mistake, they simply acted like I was the problem... Also, they over charged me for the second install. Long story long, I left without the tire and I WILL NEVER go back in that store or a Mavis tire again.
