are you using the proper charger for your unit? Sometimes using a in proper charger can cause problems like these.Did this charger come with the unit? If not, this could be causing the issue. if it is the proper charger, then I would return it for a refund or exchange. if your not using the proper charger, I doubt they will authorize a refund and you might have to just cut your losses and purchase a new one with its proper charger. hope this helps. best wishes.
