Oh, man, I hope you're doing well. They admitted their mistake in my case by sending my xmr to the address that they should have changed. Now, instead of compensating for my losses, they are delaying it. They are mean and cunning as the devil! They want me to send them a transaction from the source addresses of the exchange, which do not actually belong to me. These are the addresses of the exchange's wallets to which I do not have access. This is a mean barrier, but I have already passed validation when they sent me some xmr and I told them the amount and gave them the hash of the transaction.

I don't have to prove anything. This is their mistake, for which they must pay. My accusation is here https://bitcointalk.org/index.php?topic=5359412.msg57911052#msg57911052
