I answered and after a few seconds they hung up. I called back and heard a female recording her speech about heating and cleaning the air in my home. I transferred to a real person and "horned" him and then blocked their number.
Called Sunday, 2/21/16 at 4:59 pm PST. Caller ID showed "Buena Park CA". My phone answered by a robo call blocker which advised calling party we do not accept calls from telemarketers, to remove our number from "their call list" (legal requirement to prosecute if ever caught), or press 0 to leave message. No message left.
