Airtel — wrong number recharge reversal

Address: 577002

While recharging on paytm, i entered the wrong number and recharged 349. On querying paytm, it said to contact operator with the operator reference number (Transaction id mentioned below). Please help me reverse the amount. I have also tried 'wrc (Wrongno) (Transid) (Amt) (Correctno)' send to 59109 message. It responded as no keyword found.
I tried reaching for customer care executive through every number i could find on the internet for airtel customer care. (121, 198) none of them could give me any option for speaking with a human. Date:18/12/2017
