Problem with my messages not sending on chat.

Sorry to hear it. Unfortunately no one here can help with enforcement actions. You'll need to log in to http://enforcement.xbox.com/ and click the hammer icon. From there you can see the reason for the action
and open a case review with the PET

I hav rtried all the steps and also same problem when playing mw2 and also

2 of my friends none of us can send messages it shows messages as zero and sending invites never go through for a invite or private chat

There are a few things that can cause interruptions in your ability to send messages.

You may have privacy settings on your account that block message sending.

You may have a "child" account (under 18 in the US), and need a parent to allow messaging.

You may have an enforcement issue.

Hi I am running windows 10 and for some reason the chat option on xbox is not working. I am unable to send any of my friends messages or receive any. If i try to send a message the chat box opens but it keeps giving me a loading icon at the bottom of the
console. but I am unable to send a message.

Can anyone help me with this problem please.

It is very possible the ports for Teredo are not working or blocked (My company blocks it from a corporate IT policy). Check this link below and see if it helps.
