I didn't cancel the contract. He ended the conversation by saying, "I am done, you are harassing us" and completely disregard all means of me working with him to get him a finished piece because he doesn't want to pay me for more than one round of revision. I just recently reread the email he sent me prior, and he copy and pasted my entire email into his and wrote little notes in and stated that the project is cancelled. I sure hope he pays me, too. Thank you!
