Still Missing Founder's Cape lost back in 1.16

So, back in 2019, I was watching the Minecraft LIVE where the founders cape skin pack was released. This was when capes were announced the game and I made sure to claim the skin pack on the marketplace during the stream. Later when the bedrock beta for the capes update came out, I tried it out and saw I had the founders cape and the pancape. I was excited because I got to have 2 capes, but later when the update released, I had ONLY the pancape. I was frustrated, and I even tried getting someone to help me on this site, but I got no help on getting it back. The cape was removed from my account when the pancape was added, and I haven't had it for at least 4 years. I've I've tried multiple times to get help to get it back and no one has been able to do it. All because of a stupid glitch.

And now I found out that mojang is merging both bedrock and java capes and bedrock capes are coming to java edition. I who was supposed to have the cape dont have it. This is injustice
