Irritating out of data reminders

I have now had over 20 SMS informing me that I have used 80% of my anytime data bundle even though I have bought some more data. Highly irritating. Kindly stop.

You've used 80% of your Anytime data bundle. Dial *136*2*999# to buy a new bundle, or *135*6# to change your out-of-bundle settings and stay connected.
