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.
Keep in mind, just because the number is legit, doesn't mean the caller is!
Scammers spoof legitimate numbers to trick people into a false sense of security to answer their calls and attempt to get money or personal information from you.
This is why no one encourages others to report of legitimate numbers, as they only confuse people into believing it is a legit call when a scammer has called them and they come here to find out about the call.
