Christians Discount Tire Center

My daughter saw this place on her way home and decided to stop to purchase a tire to replace her old tire on a Friday. Monday morning she was dropping her son off at school and heard a noise that indicated her tire was flat and it was the tire she purchased the Friday before so she goes to a gas station to put a little air in it and the tire pops as she's putting air in. She goes back to the shop since her receipt says there is a 10 day warranty on the tire. The Asian and white guy go back and forth with her over it and refuses to replace the tire telling her they can give her a discount on the purchase of another tire. Well the 1st transaction was way over-priced charging her $90 for one tire then offering her to buy another tire at a discounted price of $60 when she was still within the 10 day warranty. Bad business not upholding their warranties and selling bad tires. I don't want to make it a racial thing but who knows and also the fact that my daughter is female and young (26) so I feel they got over on her because of it.
