@charlie4282 I declined the refund request with the following comment:
Hi Edward, sorry to hear that,
I’m sorry but I must decline your refund request for the following reasons:
Refund request was sent just a few minutes after the purchase (which is unlikely if the account was hacked)
I see that the item was downloaded, but you don’t mention that, and I’m afraid that the item may appear on various warez sites.
If you have any proof that could backup the fact that your account was hacked, please contact envato support and they will review your information.
Also, please read this article on refunds: https://codecanyon.net/page/customer_refund_policy#not-refundable
Thanks.
