Got call from this number. Didn't recognize the number so let the call go to the answering machine. No message was left. Getting really tired of getting these calls where no one even leaves a message as to why they were calling.

Got a call from this number let it ring then instantly after it stoped an unknown number called any info?

This is the 3rd time for this number to call I won't answer to something I don't know.

I picked up, no one was at the other end, so I didn't wait, figured it was a robo sales call, I hung up.
