Missing World Cup Twitch Spray

So, a few months ago, I collected the world cup 2023 spray from Twitch. I also had other sprays, skins, and even profile icons collected before and after this spray. EVERYTHING else is on my account except that one spray, and the Game masters have said they can’t grant me my spray I wasted 2 hours on nor any compensation for doing so. I haven’t changed my Twitch password or used anything but my phone to watch Twitch. What can be done about this? I like having all the free stuff plus it shows my dedication to this game, I guess. I love Overwatch, I just want my spray.
