I purchased a scooter. It became defective within the first week of riding. The company would not take it back and refund my money. They hang up on me when I call them. My scooter, which I rode for less than one week, is not working and sits useless in my garage. If you have any complaints with a scooter, ATV, etc. that you have purchased from them, please contact ALL of the following:

File a complaint with the California Attorney General at the following:

I also recommend hiring a consumer fraud attorney.
