I also get several daily annoying calls from 310-862-9039, but last week I started making my fax machine pick up those calls, and I haven’t received any calls from that number for a few days. This morning I received a hang-up call from 410-774-8252, when I called it back I heard the same recording I heard when I called 310-862-9039.
Actually, telephone numbers placed on the National Do Not Call Registry will remain on it permanently due to the Do-Not-Call Improvement Act of 2007, which became law in February 2008.
