Ebazar Ninja — Duplicate Power Bank received from ebazaar

I am unhappy with the product (EB 10400 MH Powerbank) received from ebazaar.
As per the details on the website, it stated that the product is of Brand - MI although the product displays "MI (CO)". Also, on using the product I observed that the power bank charges my phone only upto 80% and then gets discharged. I had used a power bank of the same company earlier with same power (10400 mah) and it could charge my phone 0-100% 3 times on single charge.

I am certain this is not the original MI power bank and would want to have a replacement or a refund of my original amount at the earliest.
