How to handle girl who’s being a bit difficult to make plans with

This is the same girl I’ve posted about a few times now. I finally was able to close and gave her a choice of sat or sun for our date. I probably should’ve Jaír went right with like Saturday at x time, but I wanted to give options just in case. She responds with a stupid excuse that seems like she’s ignoring the date kind of. I was thinking of saying something along the lines of “let’s go out Saturday night and I’ll have you back to your friends in an hour”. I think using a false time constraint could be good here because I know if we meet I can close. Any other response ideas? Thanks for the help
