Who called from 4157428829

I didn't answer; they left no message.

No message left, I called the number back from an untraceable line and number returned with a busy signal. Blocked the number.

No one is on the other end.  Nuisance call

Call from 415-742-8829.  As before, left no message.  Nuisance or prank call by someone who obviously  has no life

Call from 415-742-8829 yesterday afternoon. No message left. I never answer calls from unknown numbers as they are either IRS scam calls (IRS never calls and sends postcard or mail), phishing, marketing or for out of state charities ⁉️, etc. So annoying
