Student finance payment scheduled buy i had to make changes

Hi I found out i made a mistake in my student finance form and i had to make quick changes to curse information (i swapped from 4 year to 3 year degree) otherwise student finance would not cover my tuition fee and full maintenance loan(currently i only have only 3000) for 3rd year. My student finance account says that payment is ready to be made with in 3 working days so my question is will they pay me in 3 days or do i have to wait for another 6 weeks after making change or they will send additional payment after first maintenance is sendThanks

Hi there, When did you submit the change? Thanks, Angela.

6 days ago now i got the money and i dont know how student fiannce will deal with it also new maintenence loanis estimated to be just 6k shoud i call them and ask for higher meintenence loan or that estimated amount can change
