My mom is addicted to shopping on temu

My mom keeps buying shit she doesn't need on temu, i try to tell her to stop as it's bad for the environment and for her pocket, it's not like she has lots of money, the other way around. She has TOO MUCH stuff!! She won't listen. Maybe i can try to delete the app from her phone permanently somehow, but she'd probably just use the site or switch to shein. No idea how to fix this, she also sometimes buys me stuff even though im trying to declutter. Help is appreciated.
