I believe I found the hacker who changed my old username into the new one.
According to Transcript(1) attached in the above topic, I already told the support team my EA ID is Se7eN-ST, and they didn't even try to find. it. Of course, the hacker will change to a new one; that is why they can just type it down and hope it will appear.
Can the IT team recover my account now? I gather and provide all the evidence.
Ps. I changed my Steam name because EA support told me they can't find my name. I even provide the link to my Steam account and my Steam account ID.
