My Instagram Account Was Hacked - I Cannot Recover It for a Week

My Instagram account with the username “f***” was hacked about a week ago. I received a notification that the email address and phone number linked to my account had been changed, and since then, I have not been able to access it. I have tried all possible steps, including password reset, and also contacted the Instagram support team, but I have not received any response. My account contains personal information and photos, so recovering it is very urgent for me. I am willing to pay any necessary fee and kindly request immediate assistance.
