Who called from 3032199338

Hung up on voicemail.  I'm on DNC list.

Silence.  8/15/16 @ 5:58 PM.

The number supposedly belongs to Colorado Locksmith 24 x 7 in Brighton, Colorado.  I didn't call a locksmith. No one in my household called a locksmith. I have no idea why they would call me.

3 calls from this number over the last couple weeks - all hang ups on voicemail - no message left.  I'm willing to accept the possibility that someone is spoofing the number of a legitimate business, but to what end ?

Did not answer. So much spam!
