This is an unauthenticated user.

I have 7,000 points, so I'm planning to buy a Starbucks iced Americano at the shop.

It keeps saying "You are an unauthenticated user."

Even though I completed all the verification with the pass.

Do you know how?

The customer service center isn't answering the phone either.

I want to know how to use it.

Have you tried purchasing with cash?
