Who called from 5712616920

Was traveling for several days.  When arriving home, had calls from "ADA" under four separate phone numbers, 703-672-7732; 571-261-6920; 571-248-5690; and 571-261-6280.  No message ever left.

Caller asked for "Helen". When I said, "There is no one named Helen here" he hung up on me.

Got a call from them this morning.. the man called me by name said he was from the American Diabetes Association and asked if he could count on a donation.Then nothing more ... hung up !
