Did AT&T take the two purchases off your bill?
That's dreadful. Our landline is set so no long distance calls can be made on it, our cell phone is set for NO data, purchases and charges, and our Direct TV is set so no movie purchases nor purchases of any kind can be made.
You can tell I'm not much of a phone chatter!! Just need the basics!! 
I hope those settings protects us somewhat.
Hope your Facebook Deletion helps!!
