No, there is still something that can be done. Contacting the exchange is the first step in order to try and retrieve the funds. The exchange may have procedures in place to help you recover the funds, or they may be able to provide insight into what went wrong and how you can prevent it from happening in the future. It is important to remember that the funds are in the exchange's wallet, so they are the ones who will ultimately be responsible for helping you recover them.
