Airtel — Wrong mobile recharge - Need refund

Hey, airtel today I tried to recharge for my friend sim, I recharged it using the paytm app and I accidentally ended up typing out the wrong number to recharge, as my friend needed an urgent recharge I have recharged another time for him. I hope you can help me with a refund through paytm, thank you so much for your co operation.

I will attach the paytm invoice as for what paytm had asked me to do, thank you.
