Been getting hangups from this number for over a month.  Finally someone spoke to me (9 am Saturday!) asking if I was my x-husbands current wife then wanted to speak to my Ex.  I told him we've been divorced for 18 years and my number has changed 4 times but he kept pushing as to how he could get in touch with them.  He did tell me he was with US Recovery Services and my Ex put my number down as a contact number for him and his current wife.  I don't know how that could have happened, I haven't spoke to the man for 18 years.  I checked US Recovery out on the web and called them back.  I  was transferred to Juan Harris who confirmed that they will  call any one who seems to have any connection with the debtors for the last 25 years. Since I was married to him, they tracked down my current number hoping we still shared information.
