We have paid three months extension for our visit...

We would like to inform you that all ports are closed and it is not possible to leave now unless the emergency status is lifted
Consequently, it is necessary to review the  embassy to arrange travel procedures. If the visa is expired during the ban in the country due to the state of emergency to limit the spread Corona, it must be noted that the visa can be extended automatically
Meaning that if it is ended and the residence status cannot be corrected due to the state of emergency, no fines will be imposed on you in violation of the visa, and when the ban status is lifted, it can be renewed or leave the country without any restrictions on you

If the money was paid to a government agency, it cannot be recovered, and if it is for a company or office, yes, it is possible by filing a civil case against them and claiming it before the court. Thank you.
