Airtel — Double recharge payment

Hi,

I was recharging for my dad and first time I got an error message and no mail or message of deduction. So I clicked again, and received message of recharge but when I checked my balance double amount had been deducted from my account. So I tried reaching your customer care but as my mobile is JIO, I cannot connect with customer service. Please help me with this.
Please help me, I can’t afford double recharges.
