How to void a match when you’re losing and make it as if it never happened

Addendum) As for resolving these issues myself, I thought it might be possible to determine the outcome of the match on the server where the disconnection occurred and have it converted into a match result.
For example, if the match had been played to completion without disconnection, the win or loss would be added to the historical record on that server where the match took place. Therefore, I thought it should be resolved at the server level.
