Query: Razor Electric Scooter Has Quality Issue

We are unable to use the product though we received it almost a month ago. It seems that the battery can not function and it died 15 mins after taken off the recharge. I tried to contact Razor several times. They prefer to respond through emails. It always takes them two days to respond. Finally I spoke with someone who really could not help us much. We got their local repair contractor, which is 35 miles from where we live. When we dropped the scooter, there was another scooter in the repair place which has the exact same issue. They should not sell a new product until they solve the issue.
