"Portfolio Recovery Services" is a collection agency that is looking for someone with a name similar to yours. If you didn't talk to them, call them back, tell them you're not who they're looking for, and they'll stop calling your number.
Mark it DO NOT ANS on your phone if they do not leave a message but they have so many different numbers it will be a long list of DO Not Ans numbers in your phone if you change phones you better not use it for anything but friends and family use the other one for everything else. If you have filed bankruptcy report them to your lawyer he can stop the harassing phone calls..
Called me 3 times at 8 in the morning after I just got my sick 2 month old baby to sleep. I do not owe them a dime, they weren't even kind enough to leave a message. These people are the low-life scum of the earth. I am lucky enough to have my finances in order, I feel truly sorry for those that may be struggling only to be harassed and demeaned by these horrible people.
