Hi @Battepati Sreenivasulu ,
for payment of Azure invoices navigate to the Cost Management + Billing
section in the Azure Portal.
There you can add your payment method using your Debit Card.
If you can't get the payment done it's possible to open a support request with Microsoft Azure support. Azure Billing and Subscription support is offered by Microsoft by no cost and it's for free.
