My order no: [protected]
Complaint no:[protected]

Such worst experience ever faced on mi.com!!!

I placed an order on mi.com for product "redmi note 4 black 3g+32g" on 20th sep 2017 and pay 10, 999.00 online through my credit card.
But somehow after i placed order i want to cancel my order so, i called to mi india customer care to cancel my order but as an order is already dispatched they can't cancel the order from there end. So they told me that just refuse the order while product delivered to the delivery address. And i refused on 21st sep 2017, and then after i am waiting for the refund.

I contacted to online chat twice called customer care 15+ times but they only told me that team working on it and our representative called you but never got any call and again when i called the same thing they repeat and told wait for next 24 hours but still after 24 days there is no update on the refund.

Really now i feel help less : (
