Hello Hun,
I didn’t have my admission time to the day before either. They do usually say 48-24 hours before which is quite annoying when you need to make plans lol!
I did also have a problem with my booking as well, when I called about my admission time as I didn’t hear from them my booking wasn’t showing on the system so I had to change to a overnight case, this actually benefited me in the end!
If you haven’t heard by 11 I would definetly call them Xx
