TOTALLY Unprofessional!

So I do some contract work and I have this one person that is SUPER flaky...of course I found this out...today. I was asked to do a project and wasn't able to get to it right away because of a couple family emergencies...WELL, I asked a question and got an answer back saying that something was already done and the next one wouldn't be for a MONTH. Here's my beef...I thought this was imperative so I've been staying up all night to try and get something done. Not only that, I had to go out and buy something to complete the project thinking that I would cover the cost in a short amount of time. Now I find out that I could have waited on the item because there's no rush at all now and I won't have the money to cover it for a month. UGH! Did I mention that I have bills due?! Double UGH! At least now I know how this person is and I can put them lower on my long to do list.
