Airtel — recharged twice for 995 plan

Hello i had recharged my airtel mobile number with inr 995 and had activated unlimited pack for next 180 days had shown as failed in airtel app (Transaction done using 'google pay'.)
I had recharged the same number mistakenly of inr 995 again with my city union bank and the it got recharged twice accidently.

I contacted airtel for refund/to credit that to talk time at least as it doesn't make sense to use both same packs by paying double the price.

Now they were not ready to refund.

Does it make sense?? No matter how you pay money i was paying it to airtel.

Kindly look into this at the earliest and i am ready to provide you all yhe the transaction details as i want to find a solution for this by having the money refunded.

Thank you.
