Monster scooter parts defective battery charger right out of the box Internet, Colorado

Bought a new battery charger from Monster Scooter Parts and it was defective and did not work right out of the box!  I requested a return postage lable and a full refund of the money that it cost me!  They refused to send a pickup lable and refused a full refund even if the charger was bad!  They advise me that they would also charge me a 10% restocking fee in addition to my having to pay the shipping both ways!  They operate on Chinese Philosophy of absolutely NO customer service, what-so-ever!  In China there is no terminology for Customer Service because there is NO Customer service in China of at Monster Scooter Parts!  Avoid this company at all costs!
