CCR & Associates they are harassing me, and calling me 4 to 5 times a day Columbus, Ohio

Send the collection agency a letter via Certified Mail + Return Receipt (do not use regular mail) stating:

Per the Fair Debt Collection Practices Act, I am requesting that you cease all communications with me about this alleged debt. This is not my debt. This letter is being time stamped via Certified Mail and I can confirm receipt. I will pursue each subsequent phone call from your office with a $1,000 per incident penalty for Fair Debt Collection Practices Act violations

Next time they call, read the following statement:

Pursuant to [your state] state law, this is to inform you that this phone call is being recorded. If you do not consent to being recorded, you need to terminate this call. Pursuant to [your state] state law, continuation of this phone call after officially being informed that it is being recorded implies consent to be recorded. This recording will be used to pursue Fair Debt Collection Practice Act violations in a court of law.

You arent getting scammed.  Pick up the phone, IF THIS ISNT YOUR DEBT as you did say, and tell them.  Verify what information they have on you.  If its not you, it wont match, then they MUST remove your number.  Not answering is only telling them they have the right number.  Pick up, be cool, and when they realize they have the wrong number, you're phone wont ring again.  They do make mistakes.  They cant remove the number unless they know.  Got it?

Save yourself madness and answer the phone to find out what they are calling about.

It could be valid and if not, tell them you are on the do not call list and to never call again.
