I wrote to The Embassy of Serbia in Warsaw on March the 1st. Haven’t got a response.
Just now I made an internet phone call to them. The first guy speaks only Serbian and Polish. After hearing me saying very slowly “English” and “visa,” he transferred my call to a female colleague, whose English is.. slightly better.
In the end she recommended me to write. I double-checked the email address with her, and very slowly told her that I already wrote the other day. She said ok.
At least I’m learning how the Polish word for “dot” sounds like…
