Hit masters on Xbox and pred on switch but didn’t get pred rewards

I was pred on switch an masters on Xbox but it gave me the master rewards instead of my pred rewards from switch I tried to make a support ticket on ea but they didn’t do nothing and now I feel like I was scammed out of what I grinded for I have the proof I was pred on switch an I know they can even look it up an see for themself so I uninstalled the game an refuse to play. Does anyone know anyone or anywhere I can go and try to reach support so they can fix it an I get the rewards instead supposed to have? I held top 100 on switch an have a screenshot of me top 100 but even ea support said they couldn’t do anything even with the proof said they would send it to a game team or something like that but still haven’t heard anything i just want what I grinded for
