Someone from this number has called repeatedly and not left a message on home phone.  Assumed it was a Scam / Spam attempt if they repeatedly call and do not leave messages.  Got another call from this number, so I answered and the female caller asked for my husband by name -- said he wasn't home. She said OK... didn't ID herself. Husb called back later from unlisted number, and the person answering said "This is Nicole with Northridge Roofing" -- SO..... it appears that this is one of the fishing expedition roofer types that call around to neighborhoods and try and get business.  IF. YOU. ARE. A. LEGITIMATE. BUSINESS. -- LEAVE. A. NUMBER. TO. CALL. YOU. BACK !!!!!   ---- If you don't leave a number, then people assume you are a ripoff artist, thief, spammer, or scammer -- AND BLOCK YOUR CALLS -- like I have now done.
