Gann Lawnmower Repair

Can you place a negative star rating here? New to the area, needed a riding mower quick and purchased a craftsman used. They said the motor had been rebuilt and it a tune up and was ready to go. They even put a fuel valve on it. Spent $475 on a used mower, and $45 to deliver! They said 30 days on the motor only. Got it here, went to fill up over the 1/2 way mark and it leaked. No big deal, right? Just don't fill it over the halfway mark. 35 days, and the blades won't engage. Called them, they promised to call back. End of day, I called again, and they said it would be $20 to pick it up. WHAT? I've used the thing three times? Asked the guy if we could have it back by the next weekend and he said no problem. A week later, I call, and they haven't even touched it. Ask for a call back the next day, and had to call again at the end of the day. They want to charge me $96+ for a belt and labor. This place is a major ripoff and the customer services is a joke!
