I could not login to my Amazon.com account as I already lost my old phone number. But it forces me to login using the one-time password that is sent via SMS.
I could not access to the SMS so I clicked the Amazon Customer Service link, but it only guides me to the following page.
I manually went to the Help link on the bottom of the website, but it forces me to login which I could not.
How can I contact the Customer Service? (I don't live in the USA and could not call them...)
