Sorry to hear about his, it must be very stressful
It might not be "student support" that know the answer, at my Uni the "admissions" manage who is enrolled, who is due to be enrolled etc.
Decisions like this (usually?) have to be ratified by Academic Board, which is a formality around how Unis are run - if that hasn't met to consider your case then you will have to wait.
Again at my Uni we expect a few reassessments every summer (as a tutor I get about 2 weeks to mark them, then another week or so for moderation - so we are ready for the summer academic board which convenes to make these decisions).
You will not be the only person in this situation, there will be a process and it will have been designed to complete its decisions in good time - the only risk would be if you submitted late and the marking wasn't finished for summer board - again admissions team should know
