Hello,
Bambam. I don't know if I am not too late but I can recommend trying some chinese shops and search for high heel boots for men. They sometimes do sell "Men social shoes with heels even like 8 - 9 cm high.
I don't know if you would like them or no but that is how i started and also what i wore to dancing classes (if was a way to wear heels and looks "normal"). I know exactly what you mean by being unable to get normal heels and sadly I shared your pain untill a while ago when I changed my place of stay (on 4-month course now studying).
I personally use Wish. Can only say while it is a lower quality (tends to just be duration of the life or needing some small details fixed) it is definetly worth as a temporary solution to something longer lasting!
Good luck in your search.
