That's what I said to her, but she didn't give a crap.

That’s what I TOLD her

Ага, выбрала не то, как обычно). I reckoned так и сказала has something to do with citing someone's words. 🤔
- Ты бы ей сказала: Иди к чёрту!
— Я ей так и сказала.

In that case, yes. You can use both TOLD/SAID.

Could this also be something you told her to do and she ignored you?

Здорово! 🙏

>Could this also be something you told her to do and she ignored you?
Absolutely!

It can be anything.
- Почему ты ей не сказала, что ты уже взрослая, и у тебя своя жизнь?
- Я ей, вообще-то, так и сказала, но ей пофиг.

Aha! “Why didn’t you tell her that you’re an adult and it’s your life?” -“I did, actually, and she didn’t give a shit.” 👍🏼

Add your versions.

>I might as well have been talking to the wall.
Это же моё любимое с тех самых времён на hinative! Но мне оно не пришло на ум. 👍🙏

Hahahahahahahahaha

В одно ухо влетело, в другое вылетело. Мы тоже так говорим. 👍

I love it!
