Worst customer experience by a mile

Worst customer experience ever. By far. My delivery was split into 3. They confirmed one item as delivered but it wasn’t. When I called to find out where it is, they couldn’t tell me. They took a week to refund me. For the other 2 items, 2 weeks after I placed the order, they couldn’t confirm a delivery date. I’ve asked for the order to be cancelled and more than a week later it still hasn’t been cancelled and they can’t tell me when it will be cancelled. I called every day, multiple times a day and the story changes on every call. The customer service is shockingly poor.
