Refund my money!!

What a terrible service from Sunshine cash and carry online store. They put an incorrect image and description of their products, as a result, I ordered incorrect items. After then, I realized that the description isn't of the image, then I canceled the order. That was on the 23rd of March, today is the 2nd of April, and they are failing to refund my R964. I've been sending them emails, of which they are failing even to reply to them.
