Adobe charged me three times

<span;>I don't really know how this works here or where am I supposed to ask this exactly but I really need some help so I'm just gonna put this here.

<span;>I'm paying the "student discount" price for the "CC All Apps with 100GB storage" plan and for whatever reason Adobe charged us 3 times this month. The second one was understandable cause we were late with the previous months fee but I see no reason for the third one. This is an absurd amount of money and since I'm still a student who can't go to work cause I'm in school from 8am to 7pm my mom pays for this. However she can't keep that up if this'll be a recurring thing. (Wich is not good cause i kind of don't want to fail school) No I did not order anything new, I didn't touch my plan at all. Anyone can help me out? Thank you.
