Who called from 3123798009

I finally answered after getting various calls from various "people", all with different phone numbers.  This was Total Rewards 660, calling to tell me that I was behind in my payments.  I don't know why they feel it necessary to hide who they are.  I owe the money and will get it to them when I can.  It seems like they just open a phone book and put in a random number to show up on caller id.  
It's [***]...anybody know if this is illegal or not???

Yeah, I keep getting weird calls from this number too.

I kept getting calls from this number on my cell phone almost 30 times a day. They start calling at like 4:30 am, because my husband works midnights and he carries the phone on him. This is just stupid. Obviously, these people need a life!

Call multiple times a day between 8-9ish a day.  Same msg left under the name V. Huether name also.
