Who called from 3128770518

Comes up as wireless number. I didn't answer it and it rang for freaking ever!!

Received another call from this number this morning. My number is already on the do not call list. Any suggestions for what else can be done to stop these calls?

This number is calling here 2 to 3 times a day. I do not answer it.

Why am I getting calls from this number on my cell phone????

It's a wireless number in Franklin Park, IL that called me this morning and woke me up at 6:38AM. Called it back and says the voicemail box hasn't been set up yet.
