Something really weird happened today. Someone knocked the door , and this was a delivery boy holding a pizza and he told my dad that my number ordered a pizza from them , but I didn't order anything, and my iPhone 5s was in airplane mode the whole day , so I said this must a dirty trick from one of my friends, but more the I think about it , the more I am worried. What could have happened ? Did my phone get hacked? Or was this just a dirty trick from someone?
