Unable to Pay Monthly Fee, What Happens?

Hello everybody!

I have the following issue concerning my monthly payment to Adobe.

I made a mistake with calculating and found out I won't be able to pay my monthly fee (maybe).

Since I am currently on the search of finding a little work after school, I guess I can assume I could pay off next months' fee but what happens,

if I can't pay? Will it be added to the next month? Or will they even increase the payment for that month?

Anywho, I tried to contact the support via chat, but they said they were having server problems and I should contact them later in some hours. Unfortunately, I do not have that time today to do so, so I'll leave this here, hoping I might get a proper answer by someone who had this problem already.

Thanks in advance!
