This number belongs to debt collection group DCI. They mask their identity by using local area codes and prefix numbers. We are retired and have no debt but I do know that the person who had our previous phone number was going through a divorce because we were receiving a huge amount of calls for them. We got tired of explaining and now just ignore the numbers we don't recognize. Unwanted call blockers work well.

If the person above is correct about debt collection then that's the reason why I got this call. I have and never have had debt. So, it must be from the previous owner of my phone number.

While that might be true, the plain fact of the matter is that this DC has been known to harass people who have never owed a debt.  They target people who they think can pay them money and then try to extort it.

You need to send them a certified, return receipt cease and desist calling, or "not me" letter (think of it as the best $6.47 you ever invested).  Also send it first class mail in case no one will sign for it.  Make a notation of that fact at the bottom of the letter.  You also need to report them to the proper agencies to which I have provided links to.  Then you need to go out and get a consumer lawyer to sue them on a contingency basis (no money out of your pocket) and let them pay you for the harassment.  If everyone did these three things, these crooks would be bankrupt and we would all be the richer for it.  Use these web sites to find an attorney in your state that will probably take the case on a contingency basis (no money out of your pocket up front):  http://www.consumeradvocates.org/

You "have and never have had debt"? Huh? I think you're either missing a few words or you're confused. Perhaps you meant to say "I do not have"?
