MY PERSONAL OPINION:
I am personally opposed to leaving it to the Gods to do justice. The Gods teach Justice, they bring Justice...
...But we must fight for Justice. In life, justice is not given to us by default. You will get no more justice than the amount you can bring to your life. We have the power to do justice precisely because we can bring justice and we have the value of justice from the Gods.
Unless you just aren't skilled enough yet (maybe because you are just starting out):
In this case I cannot know who did wrong, nor I can know where they are, so my only option is the gods, I would do justice for myself but I don't know exactly who did this
If you seek Justice then God Beelzebul/Zeus is the way to go. There's no sigil for shown on the website for Alastor because this is given only by Him, so contacting Beelzebul would be best! Do His ritual and then focus on His sigil and talk to Him and explain what happend and that you seek Justice.
You can also do the same as I've told you with Father Satan.
