I have received several calls from this number (313-203-8189) in just the past 2 or 3 days...and my caller ID also says "ACS" when they call. At first, I thought it was coming from a local business with the same name, "ACS", but they aren't the type of business that would be calling people for any reason. Everytime it goes to my voicemail, all I hear is loud background noise and inaudible voices talking then they hang up and leave no message. So I looked it up today and what do ya' know....people all over are complaining about the exact same number and similar experiences with the voicemails.
This number has been calling me about five times a day. I usually ignore it, but when I do answer to give them a piece of my mind they hang up as soon as I say hello. Not a very good scam if you hang up without asking for money....just my opinion. But seriously, how would one go about getting these callers to stop?
