Konami Allowed My E-Football Account to Be Hacked During a Trade and Blocked

One trade resulted in the hacking of my E-Football account. I had been trying to sell my account, and the individuals I was working with sounded reliable, asserting they had an excellent reputation with numerous followers and solid security policies. But they instantly updated the details and seized control of my account once I revealed my Gmail and password. I found they had blocked me when I attempted to contact them on Instagram. My cousins also attempted getting in touch, but they got nasty answers before they were blocked too. Having spent a lot of time in this game, it irritates me to lose my account in this manner. I'm hoping Konami can swiftly help to fix this.
