Received 3 calls from this number today, and soon as you answer, they disconnect.  When the number is googled, it lists a business site in Florida - JM Stewart Company / Stewart Signs, but not much more info.

This is a company from Florida that makes all types of signs for churches, schools, business, etc. If you got an unwanted call it was probably because they misdialed.  As far as I know they do not make 'cold calls' trying sell.  Company name is Stewart Sign Company - Sarasota, Fl.

This is a reputable business.  I don't understand what happened with Marc and Jan 2014 post, but I'm sure it was a mistake of some kind.   It is Stewart Sign's number.

Most likely it was a mistake, but you cant rule out some illegal telemarketer spoofing their number, these do happen to both business's and  personal/private peoples numbers.

This is a reputable business.  Have done business with them after a tornado tore our church sign down.  If you had an unwanted call from them it was probably a mistake in dialing on their part.  It is Stewart Sign Company out of Florida.
