Discount Tire

I seem to have problem every time I have follow up service, first I caught them replacing only 3 tire sensors when they were supposed to replace all four this was discovered after they put the WRONG sensors in the tires. We now went in to have tire rotation, they said they couldn't do it because one on the tires had to much inside wear, we rotated the tires all 4 where fine I even took the tire in question to another shop, they laughed and said the person who said it was wear was lying to us, the wear was even and not worn down to wear marks, again I just had shoulder surgery 6 weeks ago but had to rotate tires myself, I Am a old car man for over 50 years, I semi pro raced cars and built many cars tires and all, my sons and me have bought many tires at Discount Tire, never again, as a retired businessman in the Kansas City area I will tell all not to trust Discount Tire in Liberty, Missouri
