Under what circumstances does PXP Financial give users with refused/failed deposit attempts the opportunity to re-enter payment details?

(Would they be blocked after some error messages but not others?)

User’s should receive an error message if the payment is not successful and should receive the option to re-enter the payment details. If the card details are wrong/missing, the user should have indefinite number of attempts. If the issue is with the card itself, the user can be redirected to a page were the reason is provided (for example, refused due to insufficient funds). But these are not actually error messages, but responses to the payment.
