I have purchased Powerbank, Order Id: OID395843 and Product is Combo Of Samsung 20000mah Power Bank With 3 Port USB Smart Charger Hub but the product seems to be duplicate and its not working. I opted Cash on Delivery, and I have paid the money to courier. After I received the product I put on charging and after some time it shown full charge then I tried to charge my mobile phone and it is charged only 30%, as per the product specification my phone should be charged 8 to 10 times without being charge the powerbank. So i came to know that it is duplicated product which I receive. I tried calling but their number is not reachable, I sent mail also from their website but response. Kindly consider my complaint please do needful. I am happy if I get original product.
