Unisa **** about closing dates

UNISA wrote on their website that their applications for Undergraduate close on the 27th pg September. I am applying on the 26th of September and it says all dates are closed. This is very unreasonable, because they were dishonest about their dates. I need a fair chance to apply for admission according to the closing dates they displayed on their site. Please assist me. I need to go to school next year.
