got a call from this number just dead air

this call is bothering me a lot,

I've told this caller repeatedly that I have a new number and they continue to call, boarderline harrassing...

NO MESSAGE LEFT. I HOPE THEY'RE NOT SCAMMERS BECAUSE IM TIRED OF THEIR  BULLSH8T!

I have received calls repeatedly from this caller, different numbers, for the past two years.  Same female voice recording, same message.  Have repeatedly pushed the "2" on phone to be removed with no luck.
