EA, your DNC registration ''doesn't stop them'' because it's not meant to. DNC is for barring sales callers only. This fact was not kept secret from you when you registered your numbers twice over.

If you follow those links I placed in the comment right behind yours nine months ago, you will see the federal laws and words of advice which DO apply. I'm pretty sure you've already experienced a call pattern meant to "harass or annoy", one of the FDCPA prohibitions. It is also illegal to misrepresent the nature of a debt. You've chosen correct places to send your complaints, but don't sit there waiting for a rescue those offices cannot provide.

You should have seen a required dunning letter from Capio by now. Be sure to respond with a written dispute before your thirty days pass. The same letter can also carry your wish not to be contacted by phone at certain "inconvenient" hours or to revoke call permission entirely. No need to drag out your proof of payment for now. The burden of proof rests with your accuser. Send all letters via USPS Certified with return card.

Keep detailed call logs meanwhile. The more they violate laws, the hotter your case will be if you decide to spank them in court.

This number has called me over 30+ times in the last 3 weeks with them calling me in excess of 8+ times a day on two seperate days right before Christmas. They now call me everyday once at least and it is always at lunch or dinner. I am on the national do not call list and resigned it 3 weeks ago to make sure which doesn't stop them. In searching the number I am assuming its Caprio collections. I had an idea about this and it turns out they are trying to collect $120 from a Cleveland Clinic bill I have from 2008 that I have actual physical proof of paying and the copies of the cashed checks. I was informed CC has thier own collections so I am thinking these guys are fraudulent. I will be filing a complaint with the FTC and I was advised to call the Ohio attorney general to file a complaint as that is supposedly the quickest means to an end.

If you are receiving repeated, misdirected, and/or abusive calls from a third party debt collector, you may find relief in the provisions of the FDCPA, the federal law which regulates collector behavior and provides you simple tools for your own defense. It grants you control of how you are contacted, and the means to sue at low cost. Learn your rights and first response tactics at FTC-dot-gov. See also your state laws for additional support.

Here are some jump points:

These people are fraudulent

I kept getting calls from this number but no message was left so I called back from another line and they answered "Capio Associates" which I assume is Capio Collectors, a collection agency.
