Who called from 5712928527

Keep getting calls from 571/292-8527. I do not answer since seeing the comments regarding this number.

I don't know who this is but the caller won't leave a message. I suspect telemarketer.

I answered and didnt say anything...They seem to know my name....I just sat there and let them hang up....added to my reject list.

I received a phone call from this number with a voice mail. However, there was only silence on the voice mail so I didn't return the call.

Caller called my cell phone.  I answered but there was no response.  I said hello a couple of times, but then they hung up.  I wish I could block numbers from my phone.  :-(
