Really?!? What makes you think this?
I sent in my form (although I did not give my phone number) and yet they kept coming to my door. Different people on multiple occasions. I expected to have an argument over sending it back incomplete, but they just asked the basics about how many people in the house, etc. Now they are calling me on the phone and asking me the same thing again.
Either their tracking system is pathetic or we are getting counted over and over again.
