What do I do when a previous choice of uni is still emailing about accom?

Heyo people’s,
I tried this already but this is my first time using this so I’m sorry..
Anyhow,
Long story short, I’ve got into my dream uni which is about 2 hours from home and I had so little self belief before I put my dream as a far bottom choice and made my first choice a uni that was close by because it seemed easier to get used to.
However because I was so prepped for that to be where I’d go I set up accom and everything, just to find out they rejected me and never told me and I got accepted to my dream uni,
However now despite me all ready and prepped for moving to my dream uni, I’m still getting emails about prepping for the on campus accom at the uni I thought I had to go with, except course I’m not going there… so my question is how do I fix this? I don’t know how to fix this to avoid any problems or something (I’ve never lived away from home so I know none of this to do with living out of home)
So, can I just wait?? And it’ll pass?? Or is there something I have to do?
