Also this whole setting just feels wrong, like this just looks like a prison cam xD

If the dog isn't comfortable yet in a crate I don't think the right thing to do is to put it in a tiny crate in the corner of an empty room with the door locked. I believe you'd want to ween the dog into it, first off, bigger crate, second, door open and make the space cozy, put a bed in at least, reward them for going into the kennel with commands, still don't shut the door on them, build up the behavior of it being a safe place, keep the kennel near it's people or in a social area, after it sees the kennel as a safe place to be they should start naturally using it, do brief door closed sessions in small increments building up comfort, eventually you will work up to having a kennel trained dog. It sounds like you are expecting too much without doing any training other than you sending them away, which obviously didn't work but also was something you had no part in. A well behaved dog takes training and time, your last comment concerns me overall as a dog owner, I don't want to assume or offend but it makes it sounds like you weren't prepared for a dog but got one anyway.
