There has literally been hundreds of cases reported in the media in the last few years where the phone company ported a phone number either without verification or with "verification" (easily found information) and the victim had their accounts stolen. This has been a documented problem. Phone companies seem to be starting to take the issue more seriously as of the last few months due to the aforementioned bad press. Verizon just forced me to create a PIN by Jan 24th, 2017. So I didn't have a PIN until less than a month ago.
