Replying to Will saga get mad?

So, I ordered a Large Rip city Red Jacket and Large Black pants from Saga a few months ago. Then, a few weeks later I decided I wanted to change the jacket to Anomie Blue and the pants to XL. The guy at saga told me to be absolutely sure of my change. Now I really want to change the Jacket to XL but am hesitant about emailing them another change. Will they still do the change or will they get mad or what? Anybody have an experience like this where they've changed their order a few times?
