Fortnite unauthorized purchase?

I have been playing Fortnite again for 2 days. I saved extra 2,000 Vbucks just by playing before. But a guy had my Ps4 account and then logged into Fortnite and gave himself 2 gifts from my account worth 2000 Vbucks Epic Games Support is already written well you still have tips?

Of course, now the question is, whether you knew about it (account given to a friend) or not. Whether you were hacked or not, I would definitely change your password everywhere, as the hacker also has your email address. It is best to use a different password everywhere. If you have one, you can use it anywhere but hackers, which makes your job easier.

I would just wait and see what the PSN support writes, they can help you the most.
