I don't answer from numbers I don't know. I just received this call a few minutes ago and proceeded to text them. A text back said it was a landline I sent my text to. I googled the number and my suspicions have been confirmed thanks to this.
I did not receive a call from this number but it was left as a call-back number to what the caller referred to as "First Bank". They said that there was a lock placed on my credit card and I needed to call back to remove it. The caller ID for the original call said that it was from 855-663-8674. From "United States"
I received a call from a similar number. the only difference is a 9 instead of the zero. i didn't answer, I googled the area code and 666 and found this thread.
