Mi Power Bank Deliverd By Gojavas — Regarding the one of the dead power Bank from the 2 piece combo I received

I Ordered combo of 10400 mah Power bank on Aug 21, 2015. which cost me 649 rs. I received this order on September 1 from Gojavas. One is pink and other is Black. Out of the two power bank the black coloured power Bank is not Working. While connecting to charger the indicator glow but but it doesnt charge the phone and its power Button is not working Properly. This is the first time i have Ordered something from ASK mE Bazaar and the experience is worst ever. Please change the dead/not working Power Bank (Black one) So that I can go for another Order from your shopping Site. Or else this will be my first and last shopping from Ask me Bazar. I am expecteding positive response from you.
