Who called from 4438215011

This bozo called and left 5-10 seconds of background talking noise on my voicemail before hanging up.  Sounds like a spammer call center.  Caller ID says "Maryland".

Spoofed number, scammer.

Received call July 4 about 2:20 in Virginia.  Sounded like home improvement outfit, but caller hung up when I asked for repeat of firm name.

"Call bombed" my call waiting over, and over again while I was on the phone with an important client!

Accented voice with background noise, claims to be "US Home Improvement". Asked for me by my first and last name.I hung up on them and then added the number to my call blocking software.
