Number showed as US Postal Service- I answered and it was that robot who pretends to be a real person and can't hear you. Just out of curiosity I let her speech run all the way through until she wanted to ask me some questions before connecting me to a travel consultant. Next time they call I'm going to talk to the travel consultant, try and find out where their office is and report it to the Feds for them using a number disguised as a Post Office number.
