This is Lana from Shopify. I see you are looking for a refund so I wanted to help you out here.
First of all - we are sorry to see you go! Was there a reason you decided to cancel your account at this time? Do let me know if there is anything I can help you out with there.
As for the refund, you have already taken the right first step because you have cancelled the account. The next step involves getting in touch with our support here so that we can look into the refund for you. I am directing you to our support through that link because at the moment we are unable to look into your account details through the Shopify Community.
Let me know if you have any questions here at all!
