There are numerous posts in here that would have helped you, but you seem to have not bothered to read them. Debt collectors do not sell anything, therefore they are not regulated by the DNC. They have their own special law, which has been mentioned in this thread. You should take the time tor read and learn.
Yep - this is definitely PORTFOLIO RECOVERY. I've come up with a great solution if you have AT&T Uverse. I've been using this solution for months and it works great. AT&T allows you to block calls - but only up to a precious 20 numbers. Instead of filling up your blocked call list with phone numbers from these guys, use the "Exclusive Call Forwarding" feature. This feature allows you to forward up to 20 numbers to one specific phone number. I added all the PORTFOLIO RECOVERY numbers I received to this feature instead using the limited slots of the call blocking feature. Then I have them all forwarded to 800-772-1413 which is the main PORTFOLIO RECOVERY phone number. That way, whenever they call, the call gets forwarded straight back to them. So far, I have accumulated 11 phone numbers for the last 3 or 4 months. And now I rarely get any additional numbers to add to the list. I have no idea of the legality of doing this. However, if the call is illegal to begin with, then forwarding it back to them seems to be the logical solution for the end-user. Sweet - and no call blocking slots used!! Here are the 11 PORTFOLIO RECOVERY numbers used to call me so far. Enjoy!!
