Samsung z-fold 3 debacle: what now?

[JackGats]

My z-fold 3 is 8 months old and the screen is cracking down the middle where it folds. When I bought it at Central Festival in Pattaya, I remember their telling me I had a guarantee "if I broke my screen". I distinctly remember the weird "broke" part, but I didn't pay attention to it at the time as I take good care of my smartphones. Anyways, this has nothing to do with my damaging my own phone, it's a manufacturing defect. Has anyone had to deal with this in Thailand? It's a 1500-dollar phone. If Samsung sends me packing they've lost me forever as a customer. I hope they'll offer a swap for a (non-foldable!) model. No good having the screen refurbished for it to crack up again 6 months from now.
