Got A L For A Game I Won in OT2

Played HUT a couple days ago. I matched with a PSN player and we got to OT2. I noticed my game was dropping frames like crazy although speeds stayed green and ping was 18ms. As for speeds on internet it’s 300mbps download and 59.86mbps upload with 27 latency. I was faster skating and he couldn’t score. Mostly just turned back into his own zone to reset but couldn’t get past the red line. Game was 0-0 going to OT2. I scored on a Slap shot form Ekholms ability and won. After the game I looked at statistic showed I took the loss. So I check his record and all his latest Wins are DNF with the time stat being 00:00… this seems odd to me and I have reported his gamertag. He was well known for cheating when I was on his WXCHL team in playoffs and reason we lost during that era. I’m just upset he got the win for a game he shouldn’t have. Next player he played same scenario and it was witnessed on his stream.
