According to the agreement concluded when registering with the Cryptopia Exchange, there is a point in clause 9.3 here: Generally, the procedure in which we will delist a specific Coin is as follows:
the market for the Coin is closed and from that point you will not be able to buy or sell the Coin; and
we will give at least a 30 day notice on the removal of the Coin. At that time, the status of the Coin becomes "delisting".
During the 30 day notice period, you must ensure that you withdraw the specific Coin from the Platform, to an external wallet, and cancel any outstanding Transactions. If you do not withdraw your balance of the Coin from the Platform you may lose the balance of the Coin at the time it is removed.
This item was broken, since we were not notified for 30 days, but on the same day before the closure of the coin. What can we, users, do by relying on their own rules?

I am not well versed in such matters, could you describe in more detail why they are obliged to compensate my losses? What should I refer to and where to contact? Thank.

It also came under the distribution from cryptopia.co.nz, also kept 109 coins on the wallet, the answer was only that the problem was not with us, contact the developer. I turned to him, but there is no answer. Where to go?
