Who called from 7867083820

Hi, not sure a SCAM or not!  No VM left or name associated with caller ID.  I did not answer which is my usual policy on numbers I do not recognize.

i  get calls marked unknown-i do not pick up. i pray to God, people will stop, calling my #.I i dont know dont call my #

Got a call from this number which I didn't answer since I don't answer calls from a number that I don't recognize or unknown or private numbers. No voice mail was left

A few calls from this number. I wonder who they are since no message.

It is about how to lower the interest rate applied to your credit card balance.
They play a pre-recorded message. I presume a live person comes to the line
when it ends, but I do not really know since I hanged up before it ended,
as I do not think I am willing to trust my credit card information with this people.
