Hank here from Shopify.
Sorry to hear this has happened to you after ordering from this store. And while I cannot confirm if this store is using Shopify, there is definitely a course of action you can take to help you here.
The first thing I would always suggest is to reach out to the store directly but since this doesn’t seem to be possible as they are closed, your best step is to reach out to your bank directly about this. Your bank will have measures in place for you to follow in this case and will be able to help you in relation to the payment made from your account.
We do also have an FAQ community post going through all the details of this process which you might find useful. You can see this topic here.
If you have any other questions about this, don’t hesitate to let me know.
All the best,
