回複：藥房配錯藥

"我們要把配錯的要給醫生，他也不肯，說要麽我們拿回配錯的藥，要麽拿正確的藥。" -- I think 藥房 is right here. If they gave you more than prescribed medicine, they would be in bigger trouble.

"我準備報告這事故。" -- You should. Normally, State has health department regard this. If you are very angry with the manager, you can complain to the headquarter of the 藥房.
