No feedback or refund, absolutely no customer service.

Ordered & confirmed an item 11/30/2023 (order 70507). Received an email that said my item will take 20 business days only to eventually find out it's only been ordered somewhere in China. I received my order 22/01/2024 & it's not complete. I've mailed & even included multiple pictures but with no feedback or refund, absolutely no customer service or communication. Now I'm stuck with something I can't use.
