Who called from 2135504613

how

Received voice mail fromm NCC Financial on this number

Received a call with an automated message saying "Press 1 for your message," so I pressed 1, was on hold for a few seconds and connected to someone who said, "NCC..." (couldn't really tell what the guy was saying because he was speaking very fast).

I asked what the call was about and got silence.  I asked again with no answer so I hung up.

I just got the same call.  On a phone that I just registered.  Said for English press 1, so I did and 4 minutes of hold time and I just hung up.

Unknown caller, left no message.
