Ebazar Ninja — MI 20000mah boom power bank

Address:

110092

EBazar Ninja is advertising for MI Peer bank of various capacity. I placed an
Online Order ID : OID375766 dtd.01/05/2017 on eBazar Ninja for MI 20000 mah power bank. The power bank was delivered on 04/05/2017.
The power bank charging socket is misaligned and USB charging cable pin is not going in. Hence, charging is not taking place.
Further, they did not provide any user guide and the power bank module does not have any serial number etc on its body.
I checked up with Xiomi web site and talked to their customer care officials. They say they do not sale any power bank through eBazar Ninja. Hence, it's a fake name under MI brand which belongs to Xiomi. I tried to get them customer care no. [protected] but no one picks up.
Please arrange replacement or refund.
