Funny, but sometimes finding info about a legit number is harder than finding out a scam.  There is an old saying, passed down from Antique Lands - To the Coptic Christians and then to me:
"Be not quick to ascribe to malice, that which can be adequately explained by someone dialing the wrong number" :)
Good Hunting!
