ON AUGUST 26TH 2009 AT THE HOURS BETWEEN 1PM AND 2:30 PM, I PURCHASED 20.00 DOLLAS WORTH OF SUPER UNLEADED. I DROVE MY CAR TO ROCKWALL TX. ABOUT 7 MILES FROM THAT, 711 STORE. I PARKED AND WENT TO WORK. THE FOLLOWING DAY, I STARTED MY CAR AND THE CAR WAS JUST SHACKING AND COULDIN'T PICK-UP SMOOTHLY, FINALLY IT PICKED-UP BUT NOT SMOOTH, I DROVE IT HOME . I CALLED MY MECHANIC AND EXPLAINED TO HIM WHAT HAD HAPPENED, HE TOLD ME THAT I HAD BAD FUEL IN MY TANK. I CALLED THE 711 CORPORATE OFFICE AND THEY GAVE ME A CLAIM NUMBER FOR THEIR INSUARANCE, WHEN I CALLED THEM, THEY TOLD ME THAT THEY WILL DO AN INVESTIGATION AND GET BACK WITH ME. FINALLY, AFTER 10 DAYS, I CALLED THE INSUARANCE COMPANY AND THEY TOLD ME THAT THERE WAS NOTHING WRONG WITH THEIR GAS. NOW MY CAR IS NOT RUNNING AS SMOOTH AS IT WAS RUNNING BEFORE I BOUGHT THAT CHEAP FUEL 711 WAS SELLING THAT DAY. I WONDER WHEATHER ANYONE HAD THE SAME PROBLEM WITH THE GAS THAT DAY.
