If your country is restricted from using paxful, then the registration button could have denied you from registering at the first place, bit I'm still a little bit confuse because you have used the exchange before.
I tried to verify my passport and they accept it but still the address verification is a problem because they don't accept my country, anyway to bypass that and verify the address so i can unfreeze my account ?
Your address verification would also be accepted in as much as your passport verification was accepted, it could be a problem if the country in your passport does not coincide with the address document, the simplest way of getting your address document is from your local bank statement of account,
Be persistent to complete the verification process and never loss hope.
