Default FastBoot OEM lock-Orange

Hey, just like the topic, do you have any advice?
I would add that:
-Button fastboot is locked
-I can not unlock the bootloader

The phone was purchased in orange the same hence the lock
Recently I wrote here in the forum but to no avail.

Please household remedies not services.
