No delivery, no refund, consumer out of pocket.

I ordered a few items from Manicaa in January 2022. Most of the items arrived in good order, although the delivery was very slow but this doesn't bother me too much as items are mostly imported. That said, there is one item which did not arrive in the package, and I have been waiting for this item since January 8 months ago. I have requested a refund numerous times, Manicaa insist the item will still be delivered, but I think after 8 months it is clearly not arriving - so I don't have the item, and I've already paid for it in full, and Manicaa are not refunding me ??? Very disappointed in this company, they have a lot going for them but buyer beware!
