Ted here from Shopify, thanks for reaching out to us and for letting us know.
I'm sorry to hear that you've closed your store. How did you find the platform? I wouldn't be able to guarantee a refund without taking a closer look at the account, so I've just sent an email your way there with some more info so I can authenticate the account.
If there is anything else I can help you with, please let me know, I'm happy to help!
