Who called from 2028765422

Unknown caller. No message left. Likely spam/scam.

Called 3 times in one afternoon, when answered no one speaks

They either ask if it's me answering or they hang up. Got mad that I got mad from their harassment. Longest call was just over a minute while I told them repeatedly they were harassing me.

Kept calling all day, when i answered,,guy just stammered, told him not to call my phone again, then there where 3 more calls right after that, called back, computer answered,,,,

They keep calling.  No one answered when I picked up.  I haven't answered again.  They don't leave a voicemail.  Most likely spam or scam.
