This caller keeps calling and when I answer no one is on the other line, if you call back they say press 1 is you would like to be removed from their special marketing campaigns (or something along that line) and that it would take 72 hours to be removed. Hope sooner than 72 hours because with them calling every 20 mins it is not becoming harassment.
I've received a call from this number at least 15 times in the last week. When I answer, there is no response on the other line. It then hangs up about 5-10 seconds into the call.
