Can I get a refund if the US Mission sends a password but doesn't receive a text message?

Hello, I'm glad to answer your question.

You can check whether your order is successful, and then you will get a refund. If you don't succeed, you don't need to return.

Secondly, you should make sure whether the things you buy support returning at any time. You can't return it without support.

I hope I can help you.
