Just got a voicemail from them, no call but just a voicemail (I wonder what type of technology they have).
They said they were going to delver a package from a local court.  If I was not at home (with 2 forms of ID) they would go to my employer and talk to my supervisor. I guess I will see what happens next week when they are going to deliver package.

Called then connected to what sounded like a call center with people in the background.  They then disconnected.  Obviously a computer generated call that handed me off to a person who did not pick up or reply to me.   Other sites such as callerreview.com report hang up calls as well.

They call over and over and over, disconnecting or hanging up. Never reached any live person. I've had about 35 calls from these scum bags over the past 4 days or so.

I get calls from this number daily, sometimes more than once a day.  I haven't been answering since my caller ID tells me it is 'Patriot Payments' calling.  I did answer a couple times hoping to get someone who I could tell not to call me anymore but whenever I do answer there is no one there.  

One way to tell it's spam?  The phone rings only 3 or 4 times. Since they don't want to waste time on a call picked up by an answering machine after 5 or so rings, some spammers like these have started disconnecting after just a few rings. Still annoying, but it keeps me from even having to get to the phone to look at the caller ID.
