Who called from 7792018207

Unsolicited call.
No message left.

They called & left nothing but dead air for 3:04. Wasted time I won't get back. My caller ID marked as SPAM.

Continually calls and never leaves a message have thought I blocked their calls but somehow they still get through

This # called last night (left dead air on my voicemail) & twice again today (no message left for either call today). My cell message states if I don't know the # I wont pick up & they need to leave a detailed message in order to speak to me.
I did that for a reason... take direction, or stop calling!

Received a missed call from them but do not know the number so I didn't want to call back.
