Got the same call today.  Sounded like "OBO" but could have been IBO.  Offered a lot of web services for $39/month for my listings.  I already do most of them so I thanked him and hung up.

I have received several calls from the same number so did a search and found this forum. They don't ever talk to me, just have been calling once a day for the last several days and hang up when I answer.

Yup. I got the same call. I just blocked the number.

Received a call twice in the past two days.  Never had a chance to answer because caller hung up before I could answer it.  I am a Realtor here in Sun City, Arizona so in looking at the messages I figure the caller was out to try to scam me.  Yeah right!

Refused to transfer an obvious telemarketer to the person whom they asked for.
Very rude, very aggressive woman.
Said she was calling from "OBO"
wouldnt give more details.
I asked to be removed from the list.
She pretended to hang up, then stayed on the line listening.
"are you still there"? she asked.
"Please remove this number from the list, and I am looking the number up online to file a complaint"
