FAULTY SCOOTER AND NO HELPFUL SERVICE

I bought a brand new scooter last year from a person who won it. The scooter came directly from head office Big Boy. From the start the scooter gave me trouble, everytime i took it in I was told its my imagination. I then tried to lay a complain with Big boy last year and i got no response. This year when i had trouble again i laid another complain and Sarah from head office called me the 12th of January 2016 and till date nothing was done. I have not been assisted, i was told to wait after i made it clear to hear how unsafe i feel with the scooter. I was supposed to take the scooter to a dealership of their choice last Tuesday and it broke on my way their. No solution was given when i phoned the next day. Her response was after i arranged with the dealership to take the bike in they dont have the parts - which i do understand but if a customer tells you a scooter that came from your head office less then a year ago is giving them so much trouble and that the only transport the client has to and from work is the scooter arent you suppose to atleast do your job and be helpful? This scooter leaves me stranded on the road atleast twice a week and her respons is simply i should wait
