I foolishly answered this call because "DRS ACQUISITION" made me think it might be from my doctor's office. The caller said he was Justin from Lutheran Social Services. No mention of a political candidate or other charity. I just hung up, but maybe someone is calling just making up something and then extracting credit card information. I'd stay a long ways away from these guys!
Got a call form this number today, A guy said Hello and then hung up. I called it back and got a quick/loud static sound followed by a strange digital sound then a busy signal. Wierd.
