I had an with marketplace refund too, pack I bought last year didnt work as it should and had issues, I asked for a refund, was told to contact author to fix the issues first, 3 months later it wasnt fixed still, I asked for refund again (saying i waited for author to release promised update) and got told it was too late. I basically waited for the marketplace team and the author of the asset to find out I waited too long to get a refund, even thou I was told that if the author didnt fix it soon I’d get a refund.
