Who called from 3604601927

Keep calling but when I answer there is nothing there.  Attempted to call back received busy signal.

they call few times a week...never a voicemail. I don't answer because I'm tired of hearing that I won a cruise from Captain Dan

Some automated cruise ship SPAM phone call.

how do they get your number and how can I stop these calls. calling everyday and when I call back I get a busy signal. so frustrating.

Been getting these for a cuople of weeks now. I've heard if you pick up or call back, it marks your number as an active one and will start calling more often. I never pick up, they never leave voicemail, and I'm sick of it
