I ordered 4 items, 3 successfully received but not the 4th item. No contacts whatsoever from the supplier that the item was returned to them, after 5 weeks, called Vevor and was advised that they have the item returned to them. Refund to be processed a few days after, almost 2 weeks now, still no refund for the food warmer. How can the 4th item not delivered when it's the same address as the other three???
