Received scam call from (712)-454-5004 VoIP in Sioux City, IA on Tues. 8/8/17 @ 10:14am that didn't leave a message on my unlisted phone - Do not answer unwanted annoying scam/harassing calls. Reported to DONOTCALL.GOV & FCC.GOV.

Same scam caller the previous day from (712)-454-5004 VoIP in Sioux City, IA & constant harassing hangup calls from other spoofed phone numbers - the reason I don't answer even when I know the phone number since I always check Caller ID before answering at all times of the day & night -- in fact after 11:00 pm  when I just received another scam call right now & not getting any way of blocking these calls from my unlisted phone number...disconnect the phone is the answer & permanently turn it off.
