I've ordered a new mi 10000mah powerbank that cost rs.1499 and order no. [protected]
From mi.com website on 16/07/2019 and paid rs.1499 through my sbi debit card but got it cancelled before it's shipment but even after one complete month the refund is not yet received in my bank account. Whenever i try to contact the company they say they have initiated the process of refund from their side. Now i am confused about what to do to get my money back asap.
