What can i do when my Apple-ID is hacked and my devices are locked?

This is a scam. Your Apple ID has not been hacked. Likely ransomware. They are trying to get you to pay to unlock or trying to get personal information. You may have to re-install OS to recover.

Your Apple ID has been hacked, and the hacker has used the Find My Mac functionality if iCloud and your Mac to remotely lock your Mac. Unfortunately, since this is an anti-theft feature, there is nothing that you can do about it without Apple's assistance.

First, change your Apple ID password, if you can:

https://appleid.apple.com

If you are unable to do so, you'll need Apple's assistance regaining control of your Apple ID, and will need to get help immediately, before the hacker enables two-factor authorization on your Apple ID. If they do that, you may never get control of it again.

You'll also need to contact Apple for help unlocking the Mac. Expect to be asked for proof of ownership.

Okey thank you Thomas! I Did change my password on my phone but Both of my computers are locked.. unfortunately Apple didnt have time for me so i have to fix it on my own

This is not something that you can fix on your own. This is an anti-theft feature, so it requires Apple's assistance to override it.

I'm not sure why you say Apple didn't have time for you. How did you contact Apple? Note that if you just showed up at an Apple Store without an appointment, the techs at the Genius Bar may not be able to see you, since they may have other booked appointments at that time.

Contact Apple through official channels here:

https://support.apple.com

You should be able to book an appointment at the Genius Bar there, among many other things.

Yeah, there's been a rash of these lately. If the machine itself is locked, as it would be with a firmware password, and is asking the user to contact some e-mail address, it's essentially a different kind of ransomware attack... instead of encrypting files, it involves locking the computer hardware directly.

hi there

Are you running FileVault?

Hang in, I'm trying to get you some additional help.

Firmware Password Bypass

Yes, but is it from FileVault and if it is, can you provide the FileVault (Firmware) password?

thomas-r is a security expert and the developer of Malwarebytes. He knows his stuff and you should take his advice very seriously.

I also stand corrected about your Apple ID being hacked.
