Question: I was shipped what appeared to be a refurbished charger. On top of the fact this item was refurbished, it did not work. As if the upset and inconvenience of receiving a product that does not work wasn't enough, once I returned this item to sender they had the audacity to charge a "restocking fee".

Negative
