problème de compte

Hello, excuse me for my broken English, I use Google Translate. I'm back here for help. I've already posted a message here without a response. When updating the Star Wars Heroes game, there was a bug. My son and I both play the game. We both have different email addresses, but we have the same PlayStation 4. When I updated my email address, I had my son's account and he couldn't connect to his account. After a day, I looked for ways to unlink his account from mine, then I managed to log in as a guest. On the forum, I read that you had to create a new account and make a ticket, but to date, no response. I've been looking for a solution for three days now so that my son and I can recover our accounts. Today, we are on accounts created to be able to make a ticket, and we can no longer link our previous profiles. I sent an email to eamobile and tried to make a ticket on each account, but still nothing. Could someone help us? Thank you.
