While trying to purchase reliance jio phone after entering my credit card details
The amount has been deducted from my account but bill desk error screen was shown.

A confirmation mail has been received from citi bank credit card stating 500 has been deducted from my account.

Did not receive any mail from reliance about the order failed transaction id.

Need my money refund.
