My daughter is now 15 years old and doesn't talk to us at all. She shuts herself in her room as soon as she comes home every day, and we don't listen to anything she says.

Don't blame the children for everything, but also check if you have any problems. Adolescent rebellion is one thing, but you need to know what caused it. Why don't you try telling each other what you often say to your daughter? Is that acceptable? Communication should pay attention to ways and means, only talk about your own truth and not listen to your children's ideas. Over time, rebellion will appear. As a child, she didn't resist, which shows that she is a very reasonable child and knows how to respect her parents. So, don't just "take care" of her children, but try to be friends with them, not parents. Unless there is a question of principle, other details of life have something to do with things, so don't worry about it.
