Who called from 2132455300

Got a text message about an escort service on my Android. can they be blocked. this needs to be banned!

I have received a text message about winning a Walmart gift card the last 2 night from this number, at  9:30pm and 12:20am.

i receive a message from this number, saying "thank you for shopping at Walmart!To show appreciation we'd like to offer a $1000 gift card! To claim go to....." at Dec 1, 11:45 am. I hate to receive such massages!!

Received a text Thank you for shopping at Walmart and a $100 gift card.  It so happens that my cc had fraudulent charges from Walmart.  Coincidence?  What can be done about this?
