I bought a 55 gallon Titan gas tank for my truck. If purchased before Sept. 09 I would get a $600.00 rebate to find out its a $25.00 a month if I send in a $100.00 receipt by the end of every month if I use a certain gas station. A lot of extra work but for $600.00... And still no money. I called in the beginning of Dec. and they said that Sept. and Oct. are received and checks are coming slow. Do I have any recourse?
