We actually have more control over the accounts in BDM compared to other games. But, if you lost your Google Account or any link account, that's going to be a problem.
- We and CS can't change the account link.
- If your problem is with the linked account (google, apple, facebook), you'll need to contact the CS for those platforms, not the CS for BDM.
