Charged regular Premium price for 1 month between one year of Student Discount and renewing, refund

[Furlock_Bones]

I already had the Student Discount and when it came time to renew, the first document I submitted didn't meet the standards. By the time I was able to submit an acceptable document for renewal of the Student Discount, I had already been charged the standard Premium price. Is there anyway to get a refund on the difference for that month?
