Factory Fault

I purchased a new BigBoy Scooter earlier this year and I have sent it back so many time for repairs due to factory fault and been through warranty claim after warranty claim. I am sick and tired!!! I want my money back! The latest indecent is as follows: I had the scooter working fine (by fine I mean I was able to kick start it and not electric start, and baffles loose in the exhaust). I left it like that and on the 16th on November I left for Capetown for training, leaving the scooter at home for 12 days). when I got back on the 28th I tried to start is and it was not working so I arranged for the supplier to come and pick it up and assess the new problem it has. The cam back telling me that the engine has seized. (From not working for 12 days.) I am no longer interested in getting my scooter \repaired"I want my money back! I am going to take legal action on this if I don't get what I want!"""
