I can't change the geo setting of my account

when i changed the country of my geo setting account, the changes are not applied to me and it has a bug
my acc : Iman - Realm Royale Player Stats - Realm Royale Tracker
current location of my account is Iran, and when I change it to another country, there is no change applied to my account and regional leaderboard, and I remain in the country and the flag of Iran.
I reported this problem many times in your support forum but you did not help me at all
