wallet – Bittrex drives my BTCP tokens

As some of you may remember, we had the BTC ZCL fork this year. For those who had the ZCL on the Bittrex wallet, they were converted to the BTCP, but Bittrex was not trading, but kept those chips on the wallet.
Due to the market downturn, I left my chips on the Bittrex portfolio, hopping one day to redeem the BTCP.
Yesterday, I discovered that all my chips had been lost. Bittrex has canceled all portfolios. All this was done without warning, at least I did not have one. It's amazing the amount of mail we receive from these exchanges and the important thing is to take it like that. In Bittrex's defense, they say that an email has been sent. We are talking about money here … keeping your money, this is not something you are informing by email, or you have to make sure that everyone has received the message. Imagine if your bank was doing this, it would be its last day.
I think that is the kind of attitude that makes cryptography a joke for the general public and underestimates it.
Where can I prosecute or report in Europe?
To be honest, as you can imagine, I did not have a lot of chips (otherwise I would keep it in a wallet), but it's still money. The worst thing here is the attitude, it was very disappointing.
