Mark Query, but no reply.

I am not happy with Stadio. First, the grades were released on the same day that the lecturers went on vacation. This is a major issue; how can we query our grades if we can't reach our lecturers? My grades for one of my subjects were released 3 days later. I attempted to contact Stadio to resolve this issue, but received no response. I can email you a screenshot of my call history; I phoned over 40 times. How can you solve an issue if there is no answer? I logged several q-desk tickets to different department, I still did not receive a reply. I tried doing this between the 18th of December to 22nd of December. I am also not happy because upon receiving my grades, I was surprised to find that I received a 0%. I respectfully request your assistance in understanding and potentially reviewing these results. Throughout the academic year, my performance in the course had been consistently positive, and I had diligently engaged with the coursework, assessments, and discussions. The sudden 0% grade does not align with my efforts and understanding of the subject matter. I am not happy some of my marks is not correctly captured from 15th of December till today no one answered my calls or emails to assist me. I understand that there may be errors in the system, but I am not pleased with how you respond to assisting us as students in correcting these errors. I went to hellopeter and noticed that all of the recent complaints are the same, and I am also complaining about it today; please assist us.
