It's very strange that NOBODY else has reported any calls from this number....... on ANY website. Anyway, I received 2 or 3 calls from them yesterday, July 3, 2013, and 1 so far today, July 4.  The first two calls yesterday came in during the same minute - as soon as it went to voice mail, it rang again. I didn't answer any of them because I don't know anyone in the area code or the state (Delaware). The calls come in on my cell phone and NO ONE has ever been given that number, so I can only assume it's spam or, since there isn't a single other report about it online anywhere, perhaps a wrong number.  I may answer the next time, just in case. At least if it's a wrong number, I can tell them so and maybe avoid any further calls from them.  I hope others receiving calls from this number will post here.
