Ultimately you chose to continue/start your studies with the backdrop of a pandemic, yes universities shouldnt have made promises they cant keep but when the guidance is changing every 5 seconds you should have anticipated some disruption.
I graduated in 2020 and we were thrust into this pandemic having no idea of it before March of our final year. No refunds were given so i am unsure as to why people who went in knowing the risks now want a refund. Its like booking a flight in current times, you know the risks of it changing or being cancelled.
