Bad Client Service!

I called client care this afternoon 31/10/2022. And asked the agent if I can change my delivery address because my package is not yet shipped. He informed me that is not possible, I than understood and than he said he canceled my order, I did not give him permission to cancel my order. He than just said it is already canceled. I'm very disappointed because I had items that was about 50% discount. And the money will take up to 5-7days to reflect in my account.
