I've been getting hangups every day. It's apparently an automated scheme to get you to call back.

received this call several times have never answered it, on my cell

13144333319 is a automated callback service

ne meesage. call back says nymber does accept call backs

Annoying that people can get your number and now call your unlisted cell. My policy has always been to NOT ANSWER any number I do not recognize; if it is someone I know, they will leave a message and I will return the call..........otherwise--I don't answer.  Just annoying, though, to hear the phone ring and have to check it for such nuisance calls.
