Anyone Receive a text about an evoucher credit on you bill?

Received a text message today, And this is what it read:
FRM:WLESS PROMOTIONS
MSG:Good news! We happily selected you to receive a $363.52 eVoucher applicable to your bill, please activate{Inappropriate content removed}

When you click on the link in the text, it sends you to a log in page that looks exactly like AT&T's log in page. All the links work, or at least opens a new page and directs you to the AT&T website. I called customer service to ask if it was a legitimate promotion and was told no. So I haven't really heard much back. However beware and do not provide your login information if you receive a similar text. AT&T really needs to get their corporate security to look into this before thousands of people are scammed.
