Here is Riot in its true form. When I emailed support to show them this, they asked for r3d logs. I used the website to find the right timestamp for the match in question so that I could find the right r3d log. This means it was on the website just fine. Once I sent in the logs rather than own up to their mistake they removed the match from the website and said it is not in their records.
I somewhat understand them not being able to adjust LP for the winning/losing teams, but removing it from their records completely to cover their tracks is BAD FORM.
