Who called from 3477046553

This number just ccalled me and left no message.

I don't know if there are two scam organizations at play or if there's only one, but I've gotten a huge number of calls from 347 and 214 area code numbers.

Rang once. Hung up before I picked up the phone.

Looks like scammers phishing for working phone numbers. Two rings then hung up. Don't call back on calls like this.

They always call my unlisted prepaid cell, ring once and then disconnect.  I don't answer because I recognize the number from previous attempts.
