The first text message (2/28/12 @ 12:39 pm) said: Get a free iPhone4S, enter code "FREE" at http://promodaygiveaway.com/iphone4s.
The second text said: Cash up to $1500 Fast! Go to www.LEND400.com Reply STOP 2End.
I am unsure if I should respond to the second message or not. Yes, I want the texts to stop, but why should I have to text them to stop when they shouldn't be texting me in the first place?
Due to the timing, I have to assume all of these are related, as this hasn't been an issue before to the best of my recollection.
