Hello, I need you guys help really.

I am an international student, so I don't know the typical process of US things, so please aware of this and help me

I disconnected verizonwireless service and asked for the deposit refund.

Then, the verizon wireless service sent me a green invoice, which my deposit amount is shown.

What do I do with this?

Since I don't know anything with how this refund works, currently the green invoice is just a sheet of paper that $400 is written.

I'm back to Korea and won't be going back to US there for about a year.

In my current situation, what should I do to get the real deposit? not on the sheet of paper
