i applied last week to a certain school, the good thing is i have a big chance to get employed but my problem is i dont like the environment

...there are many things i dislike the place
i was told to go back today for a daw demo to prove daw my worth... but i dont came up so the director herself called me up why i did not come...i just reasoned out that i have an emergency so i cant came but i promise reschedule it next week! (i know im wrong by telling that to her

)
ok ra bya ang mga taw but i really dont like the workplace... can u suggest me a very nice alibi to not go back next week?
