A moderator does not appear to be following the TOS. Where is the complaint form? What is the procedure?
As already mentioned by @Jamal in the comments, StackExchange provides a Contact Form, as well as an Inbox shared by the community managers.
That being said, namecalling is not really liked in such cases. If you wish to raise a complaint against moderators (who are the trusted authority in the whole network), please consider carefully whether you might be in the wrong.
You may also want to present your evidence in a calm and collected fashion. In general it's not a good idea to take aggressive stances "publicly", because you may experience a huge backlash.
