Pmc jewellery ****!

I have bought a birthday gift from them on the 12/07/2023, today is the 29/08/2023 and I still have not received my package. They keep sending me a generic email of they will receive feedback from the courier company in 5-8 days, but nothing is happening. I request a refund but they don't want to and can't give me an answer when my package will arrive. I believe its just another online ****!!!
