I'm very sorry to hear that. And it is up to @Dieze if he wants to cancel the order or if he wants you to finish it. I'm pretty sure he wants to cancel it though, so it would be great if you guys can come to an agreement in regards to the price for the service you provided until now and get it over with.
Edit: Another thing you should know is that it's not allowed to receive feedback for the work that your wokers complete. The feedback is to be exchanged between the worker in question and the client. You should also list your workers on your service thread and let your costumers know when you let one of your workers complete their order. In addition to that, you're also not allowed to share your OSBot account with other people.
TLDR: It seems like you have broken many rules today.
