Verizon $31 credit scam

Anyone ever get a recorded call from Verizon saying you were entitled to a $31 credit and to go to the website 31verizon.com?  I spent a lot of time on the phone with Verizon wireless trying to get something straightened out.  Two days later I received a call and it showed Verizon's number in the caller ID.  Gave me a message that I was entitled to a 31 credit and to go to said website to get it.  The website was dead on to Verizon, and I thought it might be legit since I just had dealings with them.  When I went to the site, it asked for my cell number, password and last 4 digits of my SS #.  When I called Verizon they said it was a scam.  It looked incredibly real and even the caller ID gave Verizon's 800 number.
