eFootball 27 Mobile Account Hacked and Network Error C_NAJM_0028

I am an active player of eFootball 27 Mobile and my account appears to have been hacked. Yesterday I noticed that I could no longer use my account properly and I started receiving a “Network Error Occurred – An invalid command has been detected. CODE::C_NAJM_0028” message on the screen. I have not shared my account details with anyone and I did not authorize any third party to access my account. Because of this situation I cannot access my account and use the g e as before. I request that my eFootball 27 Mobile account be checked urgently, that any unauthorized access be blocked and that full access to my account be recovered to me as soon as possible. Here's the email that hacked into my Kon i ID: *******@***.uk
