I need help with my hand independence/coordination in piano.

I have a major problem with hand independence, in the 7th of July I'm supposed to perform two pieces that need very good hand independence, the problem is that I don't have that, my teachers told me and I also read this on the internet that I shall practise with scales. And I did, I can play the scales very fluently however I still can't play the pieces.(primavera & nuvole bianche both by Lodovico einaudi) anyway I practised scales for nearly two months but besides I can play them fluently I can't play the pieces, I'm absolutely vulnerable , I would really appreciate your advice, suggested exercises and tips.
Thank you for your time,

I have a noteworthy issue with hand freedom, in the seventh of July I should perform two pieces that need great hand autonomy, the issue is that I don't have that, my educators let me know and I likewise read this on the web that I might rehearse with scales.
