just got a call from this number.  google voice transcribed the message as:

Hey guys, This is Sarah. I was here. Hey, We spoke on the phone last week about possibly trying to lower interest rate to reducing your monthly payments on your credit card. So I wanted to let you know that I did find a solution. We've got a program that come over those interest rates as low as 1.5% and possibly got your monthly payment in half and since you were only making the minimum payments that could be a great opportunity for you. This will be my last courtesy call, so please gimme a ring today. You can reach me here at 1(877) 723-1419 Again the number is 1(877) 723-1419.

obviously, a bad number.

Just got a call too... Man said hello and I said hello then he hung up. Actually kind of freaked me out a bit. I tried to call it back and it wouldn't even ring. I am so glad that I found this page and now know that I wasn't the only one. I will definitely not be trying to call back again

got a call from 406-623-3644 like a minute ago (12:10pm october 18 pacific time)- i picked up and sad hello?... the guy (sounded like a man in his 30s maybe?) on the other line said  "uh, hello"... then hung up on me.

This was a number I did not recognize so I rejected it.  Judging by the comments I am glad I did.  I cannot believe all of the unwanted calls I get on my prepaid cellphone.

Got a call on my  TextPlus number now 4 times from this number. I know it will be scam. No one knows this number.
