Who called from 2135364337

This number called, left no message. Unfamiliar number.

Called my cell phone.  Ranged once that hung up.  They see now block.

called- I am on do-not-call-list!!!! no message- blocked

Call came into my cell rang twice and hung up.  No message. Strange that all of us had same issue

Called at 8:04 am PST, didn't hear or see it since I was playing a game on my phone. Didn't leave a message. Not going to call them back since I think they gather call information from whoever calls back to confirm there's a real person there and not just some robot hence the initial call.
