Got a call on my cell phone and home phone when asked to leave a message they hung up

Received a call from this number. I answered and they hung up. I called back, heard a "boop" sound, and a man answered the phone. I asked twice what company they were wit and he never answered me. I told them they had the wrong number. He apologized. But when I asked for my number to be removed, he hung up. I added it to my auto reject list.

Same experience

Calls early morning  does not leave message.

Receive calls at all hours of the day & night from this number. They've yet to leave a voicemail. I answered once & they hung up. I'm assuming it's a fraudulent bill collection agency that  threatens sheriff to come & arrest you by 5 if you don't pay. This outfit has called me & family for years now from different numbers. Added to block list!
