Help, how to deal with this graduation fee from EC?

I pass the CPNE on my 3rd round, but here comes another issue,
I was told I need to pay my graduation fee 495 even I already paid 440 annual fee in March.
I try to explain my situation and to see if I can get my annual fee apply toward graduation fee.
but they said since I paid my annual fee on March, it's been 3 month now to June ( the date I pass the CPNE),
they just allow one month gap if I want take the advantages. so I still need to pay 495 graduation fee beside that 440 annual fee I paid.
I want to complain. I finished all the exam except CPNE last July, and start application on end of july. All I have is this stupid CPNE, it takes me 3 times to get through it, I paid and wait and called every day to catch any cancellation day, but it still takes me a whole year to finish it !!!

I tried one time to complain this annual fee, but I just get late fee waved.

here is their reply:
I am pleased to inform you that the waiver has been approved and the $55
late fee has been removed from your account.

Please allow me to explain our fee schedule. All students are required to
pay the Student Services Annual Fee if they wish to keep their records
active in the degree program. Our billing cycle is automated. If payment
is not recognized by the due date, you will be assessed a $55 late fee. If
payment is not received within 4 weeks, the computer will automatically
withdraw you from the degree program. Once your records are withdrawn from
the degree program, there is a $75 reactivation fee, in addition to the
annual fee that you would be required to pay to reactivate your records.
You have three months from the date your records are withdrawn in which to
pay the annual fee and reactivation fee.

Now, it's come to my graduation fee, I need some help and suggestion so I can use my annual fee more effectively.
