Bad service experience

I am experiencing extremely bad service from Milpark's student advisors. I am currently enrolling (or attempting) for my 2nd year BBA. I have been trying to complete the registration since October 2023 and still no luck. I phone multiple times a day, get transferred to my advisor and the call drops immediately. I only managed to get hold of the advisor who is 'assisting' me, yesterday, 17/01/2024. With really bad telephone etiquette, Melanie, the receptionist took my details, forwarded my call and again, the call dropped. Eventually, Zaida, the student advisor, contacted me and wanted to refer my query to a self-help zone of which I told her that is not what I need. She kept talking over me and interrupting me. I finally managed to complete my sentence, and she rep****: "Well you first need to sign and send document X". Again, I was interrupted and told her to check the emails I sent her (all the documents she required to resolve my query, I have already sent her multiple times - aren't they supposed to put all documents on the student's profile?!) It just shows you that they don't thoroughly read their emails and follow-up on student's queries. All that I need is a confirmation of registration and a tax invoice (not a proforma invoice). I am funded via a bursary and the deadline was at 4pm today, 18/01/2024. I'm not even sure if my bursary will still fund my studies. This is outrageous! I need a skillful advisor to assist me in a swiftly manner as I have a full-time job working with customers. My previous advisor (who now works in a different department) assisted me previously and I received all my documents within one week - from the start of registration and choosing module to the end of me submitting the documents. I cannot operate like this. The laid-back attitude that the staff have when answering the phone is so unprofessional and quite embarrassing I'd say. I am really unhappy. Please assist.
