Got a text message from 619-446-8721. Text said - Congratulations ..Please call 877-366-1409 to claim you $100 rewards certificate

Replay STOP to be removed  Jan 10, 12:33

I did not call to claim this so called rewards certificate or replied to the stop. Last time I did that I got bombarded with this type of text. Guess they figured out it was a legitimate number. Changed my number and this is the first one I have gotten in several months

received a text message that I'd won $100 reward certificate and it said to call a different number. This is spam.
