text said I won contest I did not enter. Am on do not call list.

Received text message saying a won gift card to Best Buy.  I have received these before and they are a scam.

Won contest I did not enter. Scam

I keep getting text messages saying I won something.  After the 3rd one I texted back, told them to take me off thier list, that they did not have permission to call or text me and that the next time they did they would be reported to the FCC.  If I get another text I'll do just that and I will file a complaint with the Florida Attorney General's office.  407 area code is Orlando, FL.
