@Basim E - Thanks for reaching out.
On top of what @Carlos Solís Salazar has mentioned,
The error related to payment verification needs to be primarily checked with your bank.
As you mentioned that you are using debit card, please make sure it has 'international transaction' enabled.
We advise our customers to use a valid credit or debit card and not a prepaid/virtual/gift card.
Hope this helps. and please feel free to reach out if you have any further questions.
