Creative Cloud billing issues...

My year subscription to Adobe Cloud ends in a month and in an email I received it noted that my monthly bill will be going up from 29.99 to 49.99, I have tried to contact Adobe by online messenger and by the phone but no response yet. I am a student at Graduate School and had been paying the student price but now with my renewal it wants me to pay more....something is not right.

If any help could be given, it would be greatly appreciated.
