I want to know the owner of this number

I get these calls in Spanish on a weekly basis. Is there a way I can stop them. The number changes from time to time.

They are trying to get money I owe them. I reported them to the FCC. I use all of my money for drugs and don't have a penny saved on the side. Stay away from drugs!

Got a call from this number in Spanish. Wish I could stop these annoying unsolicited calls.

I was in another room when my cell phone rang and missed the call.  When I checked my phone, it said missed call from this number.  Reverse phone search came back saying the number wasn't valid.  They didn't leave a voicemail.
