Who called from 2483274308

I am really getting tired of getting these calls, numerous times a day. I am on the no call list, so why am I still getting these annoying calls

Same as above. No answer, no vm, no caller ID.

Called me ,no one talked then hung up 2nd time in a week

Got two back-to-back calls from this number. Not even one complete ring before they hung up each time
