I got Extra Uru and Feather

Hello, On the first day the Side Event Quest had aired, I had somehow received double the amount of Uru and a single extra feather. I had accidentally claimed it along with everything else. After some time, I thought about it, I would receive little advantage over other players with this flaw, I would be able to play One Gauntlet more than everyone else and I would receive the Casket rewards faster than everyone else. Looking at the gauntlet rewards, it was very small, so I continued on. Stupidly played the tier 1 and 2 gauntlets, therefore losing the little advantage I originally had. Bought the tier 1-5 Caskets like everyone else. Since I had lost my first 2 feathers, I could not play the tier 6 gauntlet, I waited until reset. During this time, I would message Kabam support in search of an answer in what I would do, but after almost 20 hours, I went on and played normally without a response. When I received my 3rd feather (everyone else's 2nd feather) I played the tier 6 gauntlet and claimed the tier 6 casket. I know I had claimed it faster than all of you could have, but I would now be gaining almost exactly the same rewards as everyone else, so I thought nothing of it. Another 24 hours, and I go over to the gauntlet after claiming my now 4th feather, and I play what I suspect to be the 7th Gauntlet (I did not read which I had entered, so another dumb move of mine). Turns out, I had replayed the 6th tier gauntlet, because there was no tier 7 gauntlet to play. So I've now come to the conclusion that I am forever stuck at tier 6, to never get any more rewards from the side event quest. I know this was all stupid, but what do yall think? Anything I can do? Or do I just continue on with my mistakes? I just wanted to tell someone because I know that Kabam support will take a while. I know this was a lot to read, so any of yall who did, thank You all.
