Who called from 4803891483

refused to id himself

. . . which makes no sense.  Why call to begin with?:

I received 8 calls from this number, where I could barely hear the person on the other end. I asked them to speak up and where they were from, they hung up. I received 7 more calls (8 total) after that. All in a 30 minute period.

keeps calling will not leave a message and the number they call is suppose to be a private number and do not know how they got it.
