Automated number calls after midnight stating you have a certain amount of messages. This is quite annoying and I want it stop.

This number been calling my phone since August 9th after midnight, every 25-30mins 5 times, every night till now. I really need this to stop. It leaves a voice message stating that you have messages to retrieved and order you to  put in your pin number or cell phone number.

They call constantly asking you to check your 7 voicemails.  I am registered to the do not call list and I am concerned about how they got my number. The calls are annoying.
