Calling all hours of the morning and afternoon, and hanging up when you answer the phonnnnnnnnne

This company has called as early as 8:30 a.m. CST and when you answer the phone they hang up.  They call as late as 3 p.m. and hang up if you answer the phone, and at all times between the above given tims.  If you call them right back, you are routed to a customer service representative, and your call is "the next call in line," but they never answer your  caool  I'm not sure what they are selling because I never get to speak to a real live person, or customer service representative.

I want these calls to my house to cease and desist. I am on the DO NOT CALL LIST for whatever good that may be.  Please report these people to the FCC or whomever they need to be reported to.  Thank you very much!
