registration

Hi
Thanks for following up.
Mojtaba Zand; I am a graphic designer. I got acquainted with your site yesterday and did the initial registration.
But so far you have sent a message three times: "Your application has been rejected for a third time. Please contact our support team so that you can apply the necessary changes and start selling on PeoplePerHour."
I am from Iran and I live in Tehran, but there is no name of Iran in your location list; For this reason, I chose the names of other cities, but unfortunately my request was rejected.
Tell me how I should solve my problem. Thank You
