The number is spoofed, so calling back does no good.
Poor "Michael Sung," some lowlifes are using his faked phone number to hide behind. (You can make any caller display show any number you want, with some simple tools -- I just got a call before this showing my own phone number on caller ID).
What this call is, is a blatantly illegal pre-recorded message that does not identify the caller. They offer "dryer vent lint cleaning" for $39.95 for the first five feet. Press 1 to learn more, press 2 to be removed from their list. So I pressed 1. "All our operators are busy, please leave your name and phone number..." Yeah, right.

Called 5 times since  May 16.  Nobody there.

Has called 3 times in the last two last two weeks.  Nobody there or no message while we are out.  

Got a call just a few minutes ago from this number. It's says Beverly Hills. The call was made to my cell phone. Did not leave any message...obviously not important. Where do they get my number? I'm not interested to whatever they're selling!

My caller ID had the name Michael Sung. Unfortunately for Michael it's a blocked number.

This post updates to today's date

This # has been calling 2 - 3 times a day.  If I answer, I hear a 'click' d/cing the call.  If I don't answer, the call is D/c'ed as soon as the answering machine picks up.

Calls, wasting my time and doesn't answer.

They called trying to sell me monkey paws.

Same as above.  They call everyday.  No message. Can't call back, mailbox full.  

My number is on the Do Not Call list and this company keeps calling.
I tried to contact them to have my number removed from the call list but the mailbox was full and nobody will answer my call.

Yes same here.  I just got a call from this # and no answer.

Got 3 rings and no message

My caller ID showed this number.
