My Purchases Before the Marketplace Update are ALL LOST

Dear Mojang,
I have been playing Minecraft since I was 7 and now im 13. After Minecraft added purchasable skins before the marketplace Update, I was really happy and bought all of them, spending almost all my spare money. After the Marketplace Update however, ALL of my old Skins I bought before the Update are gone. For example biome settlers, story mode, holiday and so on. I am really devastated because first of all the skins cost a lot altogether, and second of all those were really cool skins. All the skins are by Minecraft. I bought some new skins in the marketplace after the Marketplace update, but I just really want my old skins that I bought back. Please help me, just please. Now in the store it says I have to by the skins again, but I really don't have that much money anymore and its just not very fair for me. I really love Minecraft, please help me Mojang! If you can, please restore all skins that I lost for me. They are all the skin packs made by Mojang. My XBOX gamertag is Cool Herobrine3, and I play on Android and Window 10. Again, please help me, it was a lot of money!
