Earned div 3 level on rivals, was wrongfully given div 4 rewards instead

took me a while to finally get to Division 3, when i finally went to open my rewards they told me I'm only getting division 4 rewards now (Beginner stages), because of the new season pass 6 that just began.  How is that ok when I earned div 3 finally? if you want to reset me to Div 4, fine, but at least give me the rewards for 3 that I earned. Still waiting to be helped with this.
