i order this product(as mention above) from shop clues. it is totally worst product.
1. they game wrong Color product. i ordered silver they gave me golden.
2. According to their specification product capacity is 10400 mah so, 2000 mah mobile should charge for at list 5 times but i am not able to charge even 1 time full charge .
i delivered this product on 15th oct and Return and Refund is requested by me on date 18 oct. and after requested above complaint shopclues picked up my courier. and they gave me return tracking number(As mentioned above). But with return tracking number i am not able to track it gives error. Moreover, i mailed to shopclues customer care and tried to call lots of time but asusual i am not able to contact customer care. and still they did not gave me any replay nor give my refund. Really very poor service from shopclues. Very Disappointed. I haven’t paid a money for such type of faulty product. waiting for Positive Action. shopclues always cheated to general people. now consumerforums only hope. please take some strict action so they can’t cheated to other ordinary people.
