Hi,

Bought mi redmi 4 from amazon and paid though sbi credit card (Order #[protected] price 8, 499.00. Somehow its shows transaction amount of 8499 twice in the statement. And its showing in the statement twice the amount.

I complaint through their portal email. And paid almost 10, 000 amount.
Still it's showing approx 11, 377 payment due in the statement.

I complaint 3-4 times. But they told me the amount which is debited will credited and outstanding will be zero. But still there are 11, 377 payment due
