Hi. New Here. Sorry if I break decorum with this question:

My brand new out of the box Rad Rover 6 plus has not functioned properly from the beginning. The remote on button works, but nothing lights up even though the remote on this model has its own small display screen. If I press light and down a faint "8" appears but that's it. The on button will start the bike, but will not turn it off. The display (which is separate to the remote on this model) only shows "00" even when riding the bike. (yes it does run but no setting work). THe display goes dim when I press the light button. THe light won't turn off either.  The connections seem ok.

I haven't heard back from a human. Are there replacement parts available somewhere? How can I get customer service? Any ideas on how to fix this?
