I am after a single word or maybe couple of words that we usually use to describe the situation when someone leaves us with lots of questions in our mind.
For example (this is not the exact scenario): Someone goes on holidays with some pending tasks they were supposed to complete.
I used this word before as well but can't remember it anymore. I don't think it's out of the blue, or left blank.
I requested them to call x company so that we will be clear on what went wrong when we were requesting an order, but he/she left me _______ and went on holidays.
Some more context
I am planning to use it to complain about someone's behaviour as they left me with questions and went on holidays
