They called me this am I didn't answer

I have gotten over 30 scam calls in less than a month!!! I never answer! Why can't this crap be stopped?? It is a public nuisance.  Would love to find in person just one. What &$#€%}£&!!,

808-359-2919>called my cell, on the DNCL - I did not answer & they left NO message. I called from a land line and the out going message is "The number you called is not in service".

called my cell, which is on DNCL; I don't answer calls that I do not recognize.  Of course no message left, shows on my caller id as Unknown Name.  must not be too important, so I blocked them.  if it's really important and someone needs to reach me that I know, they know how I can be reached.

They called using this number from Hawaii. Absolutely no one on the other end. Dead air. Had to pull over to answer this stupid call. I don't know anyone in Hawaii and if I did, I'd be shackin up with them. Therefore, I can only conclude its spam, scam, or salty ham.
