Alterations Snag

I brought my dress in for alterations in early July, but my wedding isn't until 9/29. I brought it so early in case it needed any bodice work (lots of appliques). It ended up only needing the sleeves taken in a little and a bustle added, I asked if I could come back in later to check that I like the fit before it's too close to the wedding. I've been losing a little weight and didn't want to pick it up in mid-September just to find that it's suddenly too loose or the sleeves still aren't right.

She is the only seamstress within an hour, and does great work for low cost (my total is $50).
I go in at my scheduled time today for that second appointment...and she hasn't even touched my dress yet. She was working on a TON of dresses for events with a closer deadline, which is understandable, but she didn't even call to tell me. It was like she completely forgot about my appointment. So I couldn't try it back on, I have no way of knowing if the fit is still good, and it won't be ready until 9/7. If it needs no other work that's perfectly fine, but do you think it would leave enough time for corrections or additional alterations?
