Hoverboard360 ripped off Internet

I bought 2 hoverboards for my Grandchildren Dec. 2016.  six months later they say there is a recall on both of them.   they want me to mail these boards back to them ( my expense) and they will not replace them but give a credit in there store for clothes.  there is not one single thing in the clothing store that they want !!!  if i wanted to buy them clothes i would have done that.   if it is recalled i either want a good board or a refund.... they will not do either one of those.  i spent over $800.00 and now have to pay the postage to send them back.;... I feel like they have completely ripped me off..   they will do nothing else for us....
