Jetson All Terrain Spin Hoverboard

I bought this as a christmas gift for my son but due to unforeseen circumstances, it stayed at his grandparents' house from winter until spring, during which time it remained packed in its original box and was never opened. When we attempted to use it in the spring, it would not hold a charge and would quit running after 30 seconds of use. Customer service told us we could not initiate a warranty replacement because the battery life was affected by failure to charge it once a month "while it was in storage." Customer service then declared the service chat "timed out" after less than a minute of waiting for my response, despite taking over a minute to respond to my messages.
