I don't know what it could be.

and in the end 2

Answer 1

RX 560 for 2GB exists: https://www.e-katalog.ru/ASUS-RADEON-RX-560-RX560-...
So you looked inattentively, since you say "All video card stores have 4gb written on the model"
If you bought in the store, then just return it back.
If you bought it from your hands, and you were told that there is 4GB, then you were deceived.
If you bought it from your hands, and they didn’t tell you that there is 4GB, then SSZB.

Answer 2

You are most likely scammed...
