Query: Terrible Purchase

I thought I was getting a good deal, when I ordered the rechargeble swivel sweeper. Unfortunately, the good deal was for the vendor that sold me the sweeper. When I received the sweeper, I tried charging the battery, with no luck. In fact, the charger got so hot, that it almost melted. I discovered that the battery was corroded and would not charge. The return policy of the vendor was so impossible to follow, that I just accepted it as money lost. I don't think the problem was the product, but the vendor selling a broken product, and not having a valid return policy.
