Airtel — refund is not received

Address:	Gurgaon, Haryana
Website:	www.airtel.in

I did a recharge for my airtel dth of rs 1499 on 6th sep 2018. Then due to some issues, i asked them to refund my amount and they initiated a refund request on 10th sep 2018 and asked me to wait till 23rd sep. But even after 23rd sep, i did not receive any refund. Then i contacted their customer care and they told me that refund has been processed successfully on 21st sep and you should confirm it with your bank/wallet.
Then i contacted phonepe and they told me that they have not received any refund request for that transaction and airtel is always closing my request without any solution. Attaching the supportive transaction details.
