Who called from 2102541130

Call came in and CID said Unknown Name. No message was left, so I have no idea who called or what they want. If it's important they should leave a message. If it's a scam or telemarketer they usually don't leave a message.

I got 2 calls from this number, if I don't know who's number it is, I'm not gonna answer, period.

Called first time. Hung up. Called 2nd time picked up. No answer then hung up. Over it. Blocked!
If I was important leave a message.

Two weeks ago I saw the call coming in with "suspected spam" on my cell phone screen. I answered and said, "I don't who is calling, but I'm on the National DO NOT CALL LIST!!! Don't call this number ever again!"  The caller hung up then.  The idiots just called my phone again!!

Didn't leave a message.
