Spanish message then a hangup

Is there a do not call list for toll free numbers?

They said something spanish, than hung up...this is the first one of this kind. I hate that they recycle numbers so very quickly. I just got this phone number, and whoever had it before me, owes money to a gazillion debt collectors...sheesh

Got a Spanish recording, saying something about giving them x numbers of dollars now in order to see your son (not 100% sure of translation, but fairly accurate).  Could be debt collectors, or something.  I live in 402 area code.

They called me twice this morning. I've had my phone number for several years now and stopped getting wrong phone number calls a while ago.
