Airtel — airtel - offer recharge done thrice

Sir..
I recharged amount of 349 three times, two times from paytm and one time from official airtel app. Initailly as the paytm payment was unable to process, i recharged it twice from paytm again. But as the recharge was again unable to process, i went for the airtel app, where it was successful for the first time. But unfortunately, after 5 mins, both of my paytm recharges were also successful.
Also 349 was a offer recharge and not main balance recharge. I would like to ask for refund of 349 +349 = 698 /- due to 3 times of recharge.

Txnid of all three are:
