I have been receiving robocalls from 661-645 numbers for the past 4 days.  It says that I'm pre-selected for something(I think Expedia?) and then asks you to press 1 to accept or 2 to be put on the Do Not Call List.  No matter which one you choose, it does nothing and then hangs up on you.  The other numbers that called me include 661-645-9517, 661-645-3055, and 661-645-1535.
