I got a text message from this number. This caller seems to know my name and address however idk this person.

Everyone's name, address, phone numbers and an abundance of personal information is available on the internet whether you want it there or not.  With all of the social nets, Rewards cards (bribes for the right to collect your shopping information),  credit cards........heck, even your Bank sells your information.  (Read their privacy disclosures and disclaimers).     Anyone can get your name and address!   Its strange to me that so many are baffled by it.
