Hankook Tire

I received my rebate card in the mail, it was suppose to be for $60. The first time I try to use it has $13.62 on the card. When I called the # on the card they tell me I have transactions on the card. I ask to dispute charges. Now I get an email with a form to fill out about the charges that I have no idea where or what they are. I can not access the information on the card because they have turned it off. Any body that had access to the card number had to be before it was mailed to me. I would like to have my rebate and warn all about hankook's rebates
