I had a caller leave a message on voicemail, stating they could rent my timeshare for $3600 a week, please call 310-734-0187, it was repeated twice very clearly, though a lot of the message was garbled and hard to understand.  The weird part was, the call did not show up on caller ID as that number, the caller ID said 918-442-0638 TELEPOLLSDOTCOM.  I have my doubts it's legitimate.

Searching this site for 310-734-0187 yields similar experiences to mine, except no one tied it to this number.
