Who called from 6572029018

I have been receiving numerous unidentified calls from numbers proported to be in Oregon and California. This number was the latest one. In each case, the caller hangs up when I answer.

called 2 to 3 times a day, hang up each time answer the phone

I have 5 calls from this number since I got a a newly activated Tracfone, Two days ago. They call at least 2 times a day stating this is about my debt and if I don't pay they will go further with it. They ask for someone I have never heard of. I just activated this phone and I don't want to have to change the number but I may have to.

This number keeps calling
