Discount Tire locations in Charlotte, NC

This has been the worst tire experience of my life. I places a order for a set of Mickey Thompson mtz I was told they are on back order and that if I could find another tire I liked I could let them know and we could get them. I found the nitto mud grapplers and liked them so after speaking with the sales guy I purchased them. I was told it would be 2 weeks until they arrive. Great that's better then a month. After 2 weeks I gave them a call because I hadn't heard from them, and after paying over 1200 dollars I wanted to make sure it was money well spent. When I called after 2 weeks I was told it would b another 2 weeks. He then said they could now get me the Mickey Thompson mtz by the end of that week or early the next week. After another 2 weeks I still have no tires and you still have have my money.
I find this very upsetting because I'm the manager at a oil place right down the street. We carry a bunch of there business cards for customers who need tires and having tire trouble. Not knowing I was setting them up for a trip to hell.
I can promise I will never recommend this place to anyone ever agian.
