Xiaomi India — amount transacted twice

Address:

Chennai, Tamil Nadu

Hello this is swedha, reporter from news today, chennai. I have ordered redmi 5a today which was a pre order and i paid for the product through debit card. First it said the transaction failed so tried for the second time and it was successfully transferred the second time. When i fortunately checked the balance i came to know that it has been transacted two times which means you have deducted rs 13, 998 for one product, i received mail which says that i have paid for only 6, 999.. Please see what's wrong and refund the extra rs 6, 999 you've transferred.
