AIBU to feel school haven't gone far enough in dealing with bully?

[Sorrythatnameistaken]

My DD has been bullied by a girl at school since Y4 (now Y6). It started with name calling, separating her from friends, online harassment using the schools TEAMS set up for online learning during lockdown and general nastiness. It left my normally confident, bubbly daughter anxious and very depressed and for a while I was really worried about her. The school "spoke" to the girl involved initially and banned her from the schools TEAMS chats - that didn't work. They then tried restorative justice (making my DD sit in a room with her while she apologised) - that didn't work. They called her parents that didn't work. They sent the girl to the school ELSA - that didn't work. For the past few months she had seemed to get bored and move on then a nasty Tik Tok video was posted about my DD which school knew about (DD is not allowed social media so luckily didnt see but others obviously did) and school again "talked" to the girl and she couldn't play sports for that day as punishment!
AIBU to think that 2 years of sustained bullying like this should lead to more?? My daughter has given up - in her words, what's the point she knows she'll just get away with it. When I talk to teachers H/teacher I'm told the girl has a "hard" home life but surely that doesn't make it ok for her to destroy my daughters confidence and school life at will???

Thanks for all your replies and sorry to hear so many have had similar experiences 😥I think I just naively hoped that they would look at it the way they would if it was their own child. I know if it was my DD who was the bully I would remove her from a situation until she could learn to behave, so to me it would make sense that this girl wasn't allowed to carry on enjoying break/lunch times, golden times etc until she sorted her behaviour out. If she uses technology to bully then she doesn't get to go on the school trip to the cinema (which she did) etc.

In terms of being able to deal with it myself - I've never actually seen the Mum - the girl walks to school - so no chance to have a conversation about it. I could write to the governors or ask for a meeting but I'm not sure what it achieves for DD day to day at this point (although I would like to drag a few teachers backsides over hot coals).

Luckily DD has managed to make a good little group of friends this year and is coping well recently but I'm angry at the message school has left her with - which is effectively that bullies win.
