I have had calls from this number also, and since someone has hacked into my phone costing me $90 in one month.  And I only use phone for calls for work from a hospital!

repeatedly calls and hangs up

How do you report these companies? I get charged for using my cell phone during the day and they keep calling me. F****rs.

Do not answer! Same "Reduce your debt..." recorded message

The same as the one above. "Reduce you debt now, for credit card or personal loans." it was in my voicemail.

Do not pick up, voicemail recorded " Reduce your debt now , to reduce press1 now, if your not interested and to  remove yourself press 2." scam obviously.
