Zoe Long sleeve Dress

I ordered a dress in good faith from the said company. Paid there and then. Was told the order was accepted and had been shipped. This was on the 18 March 2024. I was given the tracking number which I followed butt there has been no sight of such an order! I have sent the company NUMEROUS emails with NO reply nor response. If I could give a nought to them I would. In fact I wonder if they do exist? I would like my money back.
