If you don't know where you open an account, please contact your futures company. Then go to any one. The systems are all networked and can be found. The general sales department can help. It is most convenient to know people. You don't need to talk. Any friend who is not local will do.

Then find the company that opened the account and contact them. They will help you with the details. If there are any questions. Go directly to the local securities regulatory commission to complain and deal with it for you immediately.
