there's a blank spot in your story: how exactly did you react to their failures?
sarcastic remarks, expressing your 'disapproval', lecturing them about responsibility with a timer running are not helpful at all

your language seems pretty aggressive as well, expression like 'having no clue' for instance
if i had to guess i'd say that you are somewhat toxic and they are shamelessly casual
