but you get mind oooo as you have said committee was set for the selection of the prefect ship but you still went extra miles to challenge your principal with a letter but my joy is that your principal handle you appropriately but although is quite unfortunate for them to give you timekeeper instead of library prefect for some one to be given that post in school it means you are very good but with the look of things they are biased even though you do something wrong the have to call you in other first not just change your position without your notice seriously although you did well but it should have not be directly to the principal but atleast follow the proper channel as you have said
