Maybe you need to reboot for it to activate. Not just turn off but reboot. The only way I know how to do that is a battery pull. If anyone knows an easier way please let us know.
If it is an application that is being pushed, such as weather app or the like, you should have an "unsubscribe" option within the app itself. Otherwise I would try to uninstall it using the DM, resend your service books and then pull the battery. Thats how I would go about it...Good Luck, hope this helps
