Incorrect battle royale rank rewards

So I reached Masters for the first time on season 16 split 1 and ended up demoting to Diamond a little before the split ended. I really wanted the rank rewards so I checked online about this since I was too busy to re-climb back up to masters. I was told and confirmed by sources from Apex Legends that my rank rewards should be the highest tier reached of the season. After checking with others if this is true, I thought I'd be fine. Although, I ended up with diamond rewards instead... For like 1-2 months now I've been contacting ea help to try and get my correct rank rewards and to this date, I have received zero help. As explained before, my view stat page shows diamond instead of masters. This is due to my demotion to diamond. However, it should display the highest tier I reached which would be Master but it didn't. When I first checked before being able to take a screenshot, it did show however, Predator #0, which I could only assumed was masters. But it showed diamond shorty after. Alongside the view stat screenshot is apex.gg. I have explained this before but apex.gg directly shows my rank and rp gain. You can cleary see on the left that it correctly shows Master 15,220 RP was my highest tier acheived and on the right the specific dates of me reaching masters. According to the Apex Legends forums, "Tiers reset after each split and the player's final ranked rewards are determined by the highest rank reached on either split." This means that despite demoting, I should have received my master rewards. After asking players who had this happen to them, they did indeed receive their highest tier reward. Although I ended up not getting the right rewards, for 1-2 months now.
