Ebazar Ninja — Mi 20000 power bank1

Address:

313324

I have purchased a mi 20000 power bank with order id OID325511, the product is not working. I tried to contact on your customer care number but is always busy. I have also written mail to you but I have not got any reply. When I visited mi service centre they simply said me that they will not acknowledge your bills for warranty and my warranty is rejected. Mi service centre had given me all things in written, I am attaching pic of their note.
