Amazon India — worthless power bank said to be of samsung

Address:

Palakkad, Kerala, 678006

I bought a power bank through amazon from sastaprices. My order no. Was #sp[protected] dated: 11/08/2017 on cod shipment. So the product was delivered on 17/08/2017. But the power bank which was said to be of samsung make turned out to be non functional of local make. The produt details on the cover of the product was "bluetooth with free 25000 power bank" which itself was a clear case of cheating. My complaint is against amazon of jeff bezos, because we ordered for the product bestowing good faith on amazon. So it is amazon itself which has to make good our loss of money and for the mental hardship on receiving a worthless and non functional power bank.
