You feel the way you feel and feelings Are neither right nor wrong.
However I think that unless you and your T specified the timing of her reply, in her eyes this may fulfill her promise and so you will need to bring up that you feel it did not.
My T and I do not always agree on what is meant by things like "when you get back". To my T "when she gets back " means the first working day ie "when she gets back to being a T"
We've had to discuss these kinds of things.
I've found I.need to articulate very very specifically what I need ( and if course she can then say if she can do it or not or you can compromise) . if I need to.hear from her the actual day she gets back.in the country or whatever I need to very specifically state that.

So just be prepared for your T to be confused as she may feel she did exactly as you asked.
