Xiaomi India — payment deducted but order wasn't successful

I had booked the phone redmi note 8 cosmic purple with mi exchange at mi black friday sale and paid the full amount of rs. 8479 using google pay upi but the order isn't successful. When i chatted with the customer care (Mrs. Tamanna rani), she told me that the payment is deducted but it's not received at their end due to timeout. But the transaction status in my upi app shows that it's successful (Payment received my mi.com).in that case, they should initiate the refund back to my bank account but they are not doing so.

Here are my details o the same:

Name - zainil bharwani
Registered mobile number - [protected]
Order id - [protected]
Payment mode - google pay upi
Upi transaction id[protected]
Google transaction id - cicagkc2pzquyq

Please initiate my refund immediately.

Regards,
Zainil
