Amazon AWS Account Creation (help needed)

I was able to verify my credit card, but I was unable to complete phone verification(I have used various numbers, both local & international) every time I get the following message:

"Sorry, there was an error processing your request. Please try again, and if the error persists, contact AWS Customer Support."

IP is not the issue because I am creating an account from a different IP & laptop after more than two years.

What mistake am I making?

Have you tried contacting AWS Support? Maybe they can help with authorizing your payment information for your account.

No, I didn't contact them
