Hello Josh,
Thank you for using XBOX Customer Support online! I am Hazel and I will be helping you today with this issue.
As I understand, you would like to know on how to file a complaint against another player who indicated your cell number on his motto.
You can file a complaint against another player if you feel that the other player has violated the Xbox Live Code of Conduct. The other player will receive a notification of the complaint. The notification will indicate the seriousness of the allegations. Typically, you file a complaint from the Dashboard. However, if the game has a complaint option, you can also file a complaint directly from the game in between game sessions.
Note: The complaint option may not be available in all games. If a specific game does not have the complaint option, you must file a complaint from the Dashboard.
To file a complaint from the Dashboard, follow these steps:
1. Press the Xbox Guide button.
2. Under Community, select Player.
3. Select the player about whom you would like to file a complaint.
4. Select File a Complaint.
5. Select File Complaint. If you decide not to file a complaint, select Don't File to quit.
6. Select one of the following general reasons for filing the complaint:
. Profile and Content
. Communications
. Tampering
7. Select one of the following specific reasons for filing a complaint.
Note: Select the specific reason that is based on the general reason that you selected in the previous step.
. Profile and Content: Gamertag, Motto, Player Content
. Communications: Text Message, Voice Mail, Voice Chat, In-Game Voice
. Tampering: Feedback Tampering, System Tampering, Cheating
8. On the Confirm Complaint screen, select File Complaint. If you decide not to file a complaint, select Don't File to quit.
9. After you file the complaint or after you quit, you return to the Gamer Profile screen.
If you need to reply to this e-mail, please reply 'with history' (include any previous e-mail) or reference to Service Request Number ( I took it out ) so we can expedite our service to you.

I think that Filing a Complaint on him isn't really going to do much, But I did it.
I guess I'll have to wait and see...
