Who called from 21657463546

I just now got one of these calls.  Didn't get to the phone in time to answer.

This is an automated call from a security company calling on my cell phone.

How do they get a phone number with an extra digit? What does that mean????

I am on the DNC list, but it does no good with these creeps/crooks.

Why in the hell does your SIX year old have a cell phone??

Just received 2 calls from this strange number.  I answered and no one was there.

I have received 4 calls from this number today. Once I was asleep, once I had to run and catch it and then they just dialed back to back because I hung up. I finally pressed 1 and started to fuss and they hung up on me. I am on a do not call list and it is frustrating to say the least.
