I bought a drone for my son at toyzone and the very first time we tried it out,the drone was not responding to the remote then flew out of control into the sky then disappeared,tried searching for it and it didnt respond. When I went to the store to explain that there was a malfunction from the very beginning they said they can't assist me.
