How can I get a refund from a closed online store?

[AprilO]

I recently used a Shopify store for a purchase and after funds went through store was taken down, email isn't valid of merchant either

I wanted to know how I could get a refund as bank said since I ordered it and authorized it they could not help me and to go to the website payment was authorized to.

How do I get my money back... Almost 400 dollars! I am disabled and no AC as that was what I was trying to to order before the summer months.

Hey, @AprilO! Welcome to Shopify Community!

I'm sorry to hear about your online shopping experience. Please feel free to submit a report about this store so we can investigate. You can do so through this page.

We're unable to assist you with a refund, since we are not directly involved in the management of the businesses that use our platform, so contacting your bank or credit card provider is the best course of action. Most banks allow their customers to dispute a transaction within a certain time frame. Your bank will be able to clarify whether this is something they are able to support.
