Query: Worthless product - even worse support

We bought 2 of these for the grandkids. One worked for 3 days, the other never worked. When I called the support number, I was told that I had not charged it properly. I asked how to get it fixed and was told that this number was for technical service but basically they didn't offer technical service. Representative was very rude and when I asked for her supervisor, I was told that her supervisor was standing right by her and said that the problem was mine and nothing could be done. Lost $30 on this deal.
