Unjustly blocked account

Good day, it seems that no one is able to solve my problem. I log in to my Oculus Quest 2 headset using my Facebook account. However, a situation occurred where my Facebook account was blocked due to suspected violation of the rules. As a result, all my accounts were blocked, including Meta Horizon.

After a review, it was determined that I did not violate any rules and my Facebook account was restored. However, my Meta Horizon account was not restored, and to this day it is not possible to log in (it does not work via email, Facebook, or Instagram, it is not possible to log in through the Oculus headset, and it is not possible to reset the device to factory settings).

Logging in via email does not respond at all. Logging in via Facebook reports that the account is permanently blocked because the Facebook account violated the rules. But it did not violate them.

I own a headset with purchased games that are now unusable. Who will help me return my account so it works again?
