Airtel — recharge not done, amount deducted from bank.

I did my recharge for rs.558 pack through my airtel app. The money got deducted from my bank account but the recharge is not done and not reflecting in my airtel app as well. Do something about it asap. I need to know the reason behind this and want to get in touch with airtel costomer support as well. My airtel app offers no solution to such problems neither it suggests steps to be done in case something like this happens.
