broken toy

I bought one of the auto mobile police scooters mid July for my son. The Sales person that was assisting me then told me if I have any problem whatsoever with the toy before a year is up, I can bring it back for an exchange or refund. Three months down the line the scooter broke and when I took it back, the lady at customer service was ready to do a refund coz I had my till slip still. But then said she would confim with the Manager Dion, who then refused the refund. I requested to speak to Dion, he came with such an attitude telling me he would not do a refund and would rather fix the toy. My question was if breaks again I need to keep running back to the shop for repairs? He got very aggro with me and gave me such an attitude. I will never ever buy any toy from Toys r us ever again. And will spread the word to family and friends.
