Airtel — regarding refund of wrong recharge

Address:

New Delhi, Delhi, 110008

I am khushal mehta, a very old customer of airtel, my contact number is 9971*10, this number is used by my sister, so through airtel app she recharged one number added in the app that is for international roaming in doha, by mistaken she recharged it for rs 1197 which does not work in doha and we came to know once the person landed there, i request you to please refund this amount as it is a really big amount and is of no use for that person, also we recharged again for rs 647 on same number you may check the transaction as this works there. I am seeking refund for the same by requesting them, and as per the mail communication received they were supposed to contact me in 2 hours, but all in vain, i tried so many times to speak to some customer service executive, which also didn't worked as their ivr system never allows you to speak to someone
