Terrible

I go to generate an image and it won't generate nor will it say why. As im trying to make correections to what I don't know to be wrong, my free images are being deducted with each "can't generate" response. Then when images ARE generated and the body faces one way with legs going another or a body is generated with 3 arms and I hit the button to regenerate, I get the exact same images and, again, one of my free monthly selections is deducted. 

How and why would anyone pay for this?
