Bank Of India — Amount debited but order not placed and refund not received after 15 days

Address:

Vejalpur branch ahmedabad

I Ihave tried to placed order of xiomi product by upi transaction through mobikwik application.
My order not placed and amount is debited. I have complained to xiomi. Xiomi replied that payment is stuck in your bank. So i have done application to bank of india branch for charge back request.
I have called to upi toll free number and as per their suggestion, i have emailed details to Support.[protected]@bankofindia.co.in
They told me to reply in 24 to 48 hours.
But still not get any email reply from bank
I have also filled form in grievances section of website, but still not get any reply.
