I got the exact same phone call. I do not know what to do as well. They keep calling and are threatening to try and mess up my credit.

My daughter got a call on her cell from this number saying she owed $80 from over a year ago for acai berry.  They wanted her to give them a credit card number, she was scared and called me at work. Lucky she does not have a credit card at 16 years old.  Im so mad, I want then to call me!!
