Took my money for an order that they never delivered and then cancelled the order without a refund. They do not respond to emails

Orders a number of prints from them. Got no indication of delivery time. I emailed them, no reply. Got an email from owner apologising months and months later and to tell me my prints would be sent to me shortly. Then nothing.

Then an email telling me my order was cancelled by them and that I was not refunded. I emailed asking for a refund. No response.

I will be taking this to CPA next.
