I have staked USDC on a centralized platform that has reinvested it into UST...
To be exact, a smart contract has converted the USDC to wrapped UST and staked it on Anchor.

Due the collapse of Terra Luna the funds were lost, the support of the platform said.

I think in order to make a claim on my insurance (yes, lucky I had one), I need to send the devalued tokens to the insurance as a proof.
Then the DAO has to vote whether the claim is valid or not.

I have kindly requested my worthless tokens back, but at the moment it seems like my support tickets are being ignored.

My question:
Are the platform operators obliged to send me the worthless wrapped UST?
Does anybody know a lawyer in the blockchain field, just in case they will continue ignoring my tickets?
