If the owner does not want to pay you for work you performed, you should be liening the project. More information is needed to assist you with this matter, please remember, this is time sensitive as your lien rights can expire. In sum, it sounds like you're not getting paid unless you lien the project, I doubt the owner is just going to "change their mind" otherwise; regardless, more information is needed.
