Help with Amazon Account?

This is a real shot in the dark, but I’m wondering if by some miracle anyone knows a human who works for Amazon.

This is my problem: I emigrated from South Africa to Spain and forgot my Amazon password (yeah, back then I didn’t know about LastPass etc.).

Every time I click the “forgot password” I receive the email with the reset code just fine, except that as soon as I enter it I get an error message that states that my account has been temporarily blocked because they have detected suspicious activity and to contact customer service.

I have scoured the internet for a way to contact customer service, have sent emails and left messages for months but haven’t received any reply.

I’m very tempted to simply open a new account, but I have been warned that Amazon could block me for life if I do that. Apparently, you can only have 1 Amazon account for life. Is that true?

I honestly don’t know what to do. Any advice would be greatly appreciated.
