Lulu here from the Shopify Support team. Thanks for reaching out here, and I'll be more than happy to help you out.
I can have a look into this and see if you are eligible for a refund. In order to do so, I will just need to verify your account. I will send you an email to the email address attached to this forums account and confirm some security questions about your store. Once you reply to that email, I can check it out for you.
