Worst experience/ poor service and communication

I am writing to express my deep concern and disappointment with the ongoing issues I’ve been experiencing regarding my module changes. Despite multiple follow-ups with student advisor, I have not received the assistance I need. And my modules have still not been updated I had clearly communicated earlier that I would not be able to afford the payment amount quoted R3000). I had requested a course change that would suit my financial situation (Bcom honours human resource management). I kindly ask that this matter be treated with urgency because i want to start with my assignments. Please help resolve this issue as soon as possible. I am still committed to my studies and would appreciate the opportunity to succeed with the proper guidance and support.
