Gomera Rivera - Añasco, Puerto Rico

They replaced a tire on m y car with a used tire. The replaced tire was defective and went flat before the 48 hour warranty on used tires. They refused to replace it and stated it had to be my fault because "tires go flat in less then 12 hours" and mine lasted a day and a half. The "fixed" the same used tire which is visibly all cracked on the walls. As I pointed this out they said that was not a problem that it is only cosmetic. There claim was that I punctured the tire although they could find nothing wrong they smeared some black tar all over the inside of the tire. Fooled me once...shame on you. Won't get me twice.
