[Resolved]  Ebazar Ninja — MI powerbank 20800mah non function

Address:

Dear Sir,
Recently I purchased a Power Bank of MI 20800mah through E Bazar. Accordingly delivery of the PB made on 9th Sep 2016. I have opened it and insert the cable to charge PB through CPU. After charging a period of 4 hours, the PB found not functioning. Even no manual about how to use or guidelines. Twice I made the experiment, even though the PB not functioning. My details are:
Name Raghavendra BV

Due to my work presure and Retail Invoice misplaced. Hence, I could not file any complaint in this regard. Today I tried to contact twice, but all lines are coming buzy. Kindly replace the same or advice about further course of action in this regard.
