Final Grade Argument For Class

For my final grade argument I am asking to change my F to a C. The reason for my low grade in class was due to a technical error on Canvas. It may sound like a stretch to ask for a two letter grade increase but I made it to class almost every day, payed attention in class, and I turned in all work I possibly could.
The reason it took so long to catch on to the malfunction on Canvas was because on the website it would show that I submitted the work that was due at the time, but my teachers were not receiving it. During that time it was down in class we were working on our first rhetorical analysis which was heavily weighted. I took a big hit to my grade because of that, but luckily I caught the problem before more damage to my grade could have
