Is there absolutely nothing I can do outside of creating a new account and buying the game again? 

Also that's a weird attitude. Sorry you got robbed, get better locks next time.

In 2017 my account MrChilliBean02 was hacked. I sorted it out, got my account back and didn't think too much of it. However, I recently got back into BF4 and found myself getting automatically banned from certain servers. The reason being, my account has likely been used for cheating.

Now it may well have when it wasn't in my control, but I was hoping I could sort this out so I'm not banned on sight in the future. I admit my mistake in being lax with security, but I don't really want to lose my entire profile because of the actions of someone else.

Thanks in advance.
