Video generation didn't use my starting frame as reference and could not be stopped so it took my credits and gave me no video.

Tried to generate a video with a starting frame. Frame disappeared once I clicked generate and the resulting video was completely wrong. Tried again and the frame disappeared again. Tried to stop the video by closing out or refreshing and it took my credits anyway and did not even generate a video. At the very least allow a generation to be stopped maybe with a few second delay before taking credits and starting the video generation. I have complained/suggested this before and was told to close out the page to stop the generation, but it's pointless if it still takes my credits.
