FaceTime on my WiFi iPad has given me a phone number that isn't mine. I can't seem to edit it.

Hi:

I have a current generation WiFi ipad that has just been updated to the latest IOS. Upon reboot, I learned that some weird phone number has been associated with my Facetime account.

This is not my phone number.

This isn't even a phone number in my address book.

I can change the Facebook contact selector to my e-mail address but how do I get rid of this phone number. I cannot seem to edit it on my iPad. Facebook on my Mac Pro doesn't seem to have preferences enabled.

Wilco Tango Charlie?
