Hello Srithika

Sometimes it happens as money will be deducted from the account but the payment will not be received from the receiving end.

SO, it's my request before making any payment just call your bank customer service and ask them wheteher the payment has been received by receiver or not.

If in the application status it is still showing "Payment due" then you have to make a re payment.

It happens sometimes in food apps too and anywhere where online payment is done.
