You were fighting a losing battle because you left and then came back claiming damage. Most businesses nowadays are more cautious about these things since there are lots of people trying to get something for free. They do not know you and they cannot read minds.

DT is the ONLY place I take either of our cars for tires and have bought 7 or 8 sets from them over the years and they have ALWAYS treated me right and gave me a good price.
