Tried to purchase tires at Discount Tire by check....

Tried to purchase tires at Discount Tire by check. United Tranzactions disallowed the purchase. No reason was given, and the store employee was unable to request one. I have never written a bad check, and my checking account balance was more than adequate. The only reason I gave them even one star is that the system won't accept zero. Hey United Tranzactions, why don't you do the country a favor and go out of business.
