Airtel — recharge not reflecting in my account

Recharge has been done for my airtel prepaid mumber on 15.4.20 for 499 but still can't find that reflecting in my account.. Either refund my amount or process the transaction. It is very difficult to reach out to customer care as none are connecting. When the essential services are working with very limited resources why can't such a big company have customers care executives who can handle customer grievances. Sick of it airtel. Three days and my recharge is still pending.
