Airtel — recharge amount debited but not loaded

I have done a recharge through airtel thanks app of rs 598 via google-pay. Recharge amount is already debited but it is not showing in my account neither i didn't got any message related to recharge done.
I have emailed several times but i'm not getting reply. I am just getting computer generated reply.
The validity of my mobile number is going to be end soon. I'm just getting messages for doing the recharge again.
It's not about amount but it's about irresponsible behavior.
I just want my recharge pack or
At least give my money back.
