Scam call, caller calls my phone all the time.

Same deal here. Calls 3 times in a row with message "you have one complaint filed against you", "you have 1 chance to call" etc, etc. gives a case number. The incoming call shows "unknown", 626-346-2930 and 626-346-8278 are the call back numbers they've given so far. When I called the number, I asked for a business name, address and main business line number. I was told that such private information can't be given over the phone because I could be a terrorist?!?! This coming from "Mark Edwards" whose English is mediocre at best.
