Unable to rate apps iPhone

Hello,
I have the Verizon iPhone and Ive been trying give rate/reviews to my installed apps. But when I click send (after writing a review or rating), nothing happens, it just returns to the same screen. I do not get a click to rate pop up and when I close out of the app store and go back in, my review and ratings are still there. Any suggestions, fixes?
