Unexpected Bill

You have to login AWS console and then go to support center, open a support case under Account&Billing category. Support team will guide you how to stop unexpected billing. https://support.console.aws.amazon.com/support/

Also, for future in order to avoid getting into this situation, please setup budgets and alerts so that you get notified if some of the resources were left running and ended up stacking up huge bills. Refer to below link on how to do that. https://docs.aws.amazon.com/cost-management/latest/userguide/budgets-create.html

With budgets setup, you can be proactive vs reactive.

Also this forum is more of a user forum and not a support centre where someone will actually work on your issue to resolve your pending invoice. Like other folks mentioned, you may want to create a ticket with support and work with them.

Hope this helps

I am using aws as learning. But i have no knowledge about billing. suddenly i saw aws billing dashboard Amount charge please remove this amount because i am a student. I have no money to pay this amount

You will need to open a support case via the console: https://support.console.aws.amazon.com/support/home#/case/create.

I would also recommend that you will check in the bill to see where the charges are coming from and stop the relevant services.
