EssentialsX-2.0.1.jar
Minecraft 1.8 - spigot

I have ran the command pex user [username] list [world] from console

I have the following from a log file
[14:08:11] [Server thread/INFO]: [username]'s permissions:�[m
[14:08:11] [Server thread/INFO]: bukkit.command.op.give�[m

From the looks of that the user would not have access to the feed command. However when it was ran I got the following
[14:07:18] [Server thread/INFO]: stoi2m1 issued server command: /feed
and in chat after the command was ran
Your appetite was sated

Does any one have any info which would help me determine why I can not disable the feed command?

So after writing this I disabled my perms plugin and loaded with just essentials controlling the use of the commands. I found I did not have access to the feed command any longer. So I must have something messed up in the permissions somewhere.

Is your server in offline mode?

if you are talking about the online-mode (vs the offline mode). I have it set to false. I believe this is set to false since I am running bungee.

Problem Solved:
Looks like it was a perm issue after all. I was using the wrong negate character. I was using ^ which was used on the previous permissions plugin I was using when I should have been using -. Thanks for the help.
