Same scam. "David Grey" leaves a threatening message directing me to call him at 915-208-4342 regarding a Treasury Department action on a pension and that ignoring the call constitutes a "second attempt" and ignoring the summons.
Ha! I called to try to put them on. (my caller ID is blocked.) A woman with a thick Indian accent answered. I asked for david grey, and she said something unintelligible about where he is. I asked her three times to repeat. then she asked if i was calling from this number, (she had my corect telephone numbe) and asked if I am jeremy XXXXXX. I said, "How did you get that? This is amazing! What's going on?" She disconnected. I guess they're used to people wasting their time. I'll try again later. I may get raunchy!
