8 Months waiting for a refund

I made a purchase in March 2023. And 2 items was not working, I followed the steps to return the item. I was told I would get a refund but its now the 23 November and now I'm told I will get credit on the profile. But don't want the credit I want the refund as I was told. Why is that they get to change there story 8 months later. The items didnt work and I wany my money back. that it.
