Xiaomi India — mobile handset xiaomi india money debited from account but not refunded

Address:

185 c block 6th cross devraj urs layout, Davanagere, Karnataka, 577001

I have ordered redmi note 8 pro on 29th nov 2019, money deducted from my debit card but order was not placed.

When i contacted mi customer service they said that money has not been received and transaction was failed due to time out error.
Then i contacted bank they investigated and provide me proof for transaction being successful and merchant has received at their end.

Again i contacted mi customer support this time they told me that amount not received.

When i conveyed the same message to bank they are showing the proof that merchant has received money.

I am become sandwich between merchant and bank and suffering from last 17 days. Both are blaming each other for action items. No one providing proper resolution to the issue.

Kindly help me in this regard.
