Someone Stole My Konami Efootball Account

I have been using an eFootball account on my Android phone in Kenya, and on 9 June I lost access to this account after being tricked by someone who said he wanted to buy it from me. Trusting this person, I shared my email and verification codes with him so that we could proceed with the transaction. After I gave him this information, he changed the email linked to the account and added his own, locking me out completely. Since then I have not been able to access my eFootball account, even though I still have the account details such as the email I originally used and other information that can verify I am the real owner. I kindly request that my eFootball account be recovered and returned to me, that the other person’s email be removed from the account, and that this person be investigated and banned if possible, because I believe this is probably not the first time they have done this. I am ready to provide any information you may need to confirm my ownership of the account so that it can be restored to me as soon as possible.
