is there a chance of getting robux back after purchasing a gamepass?

HEY everyone. so my little cousin was using my roblox account since i left it unattended on my playstation and they ended up buying a gamepass worth 799 ROBUX and i saved up to get robux ahhh.

anyways, i'm posting to ask if there's a way to get some sort of a refund? am i cooked??

UPDATE : just messaged an admin of the game and they said they could refund. so guys, if you’re in a similar situation to me you’re likely NOT cooked!!!
