My Account Is Hacked

I am writing regarding a serious problem I experienced with my Efootball Mobile account, which was hacked yesterday. I suddenly lost access to my account and all my game progress, and despite my attempts I have not been able to recover it. I contacted Efootball/Konami support and informed them that my account had been hacked. However, the only response I received was that there is nothing they can do other than suspension. This answer is extremely unsatisfactory for me, as I am the victim in this situation and I am losing an account that I have spent a lot of time and effort developing. I request that my hacked Efootball Mobile account be investigated in detail, that the access logs and unusual login activities be reviewed, and that my account be restored to me if possible. At the very least, I would like a clear and transparent explanation of what can be done to recover my account and protect it so that this does not happen again.
