ACCEPTENCE OFFER CHANGED TO COURSE FULL IN LESS THAN 20 HOURS AND NO HELP FROM ALL DEPARTMENTS

I had apply for Higher certificate in Dental Assisting and went for interview and evaluation test. Monday 2025/01/20,22:30Pm i checked my status on portal and it said “accepted” when i check on the following day so i go an pay registration fee, i find out that status changed to “Course Full” and this is for a second Time now even on 2024 i had same issue. Tried to contact Department but no Help at all -I full qaulify for course and meet all requirements at an extended Level My id Number : *** My student number: *** Course app**** : HCDA101
