Who called from 3604776873

Yep, same for me.  I'm an ATT customer. I tried calling the number back from a called ID blocked landline and I get a busy signal.

Keep getting calls from these people almost every week. Didn't answer call, no message was left. I'm a Verizon Customer.

Me too, same issue,  calls always hangs up... WTF

I dont answer calls for #s I dont recognize.  No message left - assume its some type of cold call scam.

Keeps calling and never leaves a message. I have not answered yet but its probably a telemarketer.
