When a channel or account is terminated, you'll receive an email with more details about the reason. If you think it happened in error, you can always appeal. Here's more info about account terminations, including why it can happen: https://goo.gl/wi7Ubg
Just to confirm, have you already appealed the account suspension? Also, as you've already contacted our Creator support team via email, someone from our team will update you via email as soon as the review is completed. Thanks.
