Who called from 4048915230

Received a call at 2:30 pm today. After I said hello, there was no one there. I said hello again and then a recording said, "Good Bye" and then call ended.

ADT security called and asked for me.  I've never done business with ADT, so this was either a telemarketer or phishing.

LIKEWISE, THEY JUST CALLED ME.  I DIDNT ANSWER.

they called me too...i got an recorded message that just said "good bye."

Don't worry, people can't access that information, and if they could, they would be smart enough to not let the number be seen on caller id. You are probably safe. If they call again, call them again and again...they will get the message, and not call anymore.
