Texture pack and skin problems

Hello Mojang. 

I was playing Minecraft one night when the texture pack + Skin pack that I had bought disappeared. My equipped skin disappeared (from the pack that I bought), and the world that had the texture pack applied was reset to the normal texture pack. I tried to close my window in case it was a small connection issue, but after closing the page and reloading it more than five times, the pack failed to load. I visited the store to see if something had happened, and the game told me that I need to purchase the pack again, despite me already paying for the pack. The texture pack is called Super Cute Textures Pack by Minecraft. I had purchased the pack a while back (I can't remember the exact date, but it was sometime around July 16th, 2019).
