Athabasca University

I signed up for a course at ATHABASCA UNIVERSITY on July 31st, with a start date of September 1. On September 16th, I sent a course withdrawal request form through regular mail. The form was dated September 14th. I followed the instructions on the form to withdraw from the course within the first 30 days in order to get a refund of my tuition fees. However, when the semester ended and I still hadn't received any confirmation of my course drop or a refund notice, I contacted the school for an update. They informed me that they hadn't received my request. They said I could still drop the course, but I wouldn't get a refund. I decided to appeal their decision, but unfortunately, it was denied. They claimed that I couldn't prove I had mailed the form on the date I claimed, and they also mentioned that it was my fault for not checking the status online. I have two issues with this situation: 1. The website and form didn't mention that the request had to be sent by registered mail. 2. If I have to check the status online, why do they even provide a paper form? There is no information on the website stating that I must check the status online. This is the website I used:
