I've been charged the non-student price for Creative Cloud, despite still being a verified student.

Hello.

I've been using the student Creative Cloud - all apps plan, which was £16.24 in the first year, then increased to after the first year £24.96, as it said on the plan. 

A week ago, I was emailed to re-verify my student status so I can keep using the student plan, which I did. Despite verifying as a student, I was charged the non-student price of £49.94 for Creative Cloud - all apps. 

I thought there was a mistake, so I cancelled the plan, as I should be paying £24.96.

After cancelling the plan, I contacted support about my eligibility for a refund, as I was charged the non-discounted price. I was informed that I was not eligible, and I have also lost access to the Creative Cloud, paying £49.94 for nothing. I was informed that I can buy the student subscription again, but doing so would mean spending an additional £24.96 on top of the £49.94 I've already been charged, just to use the software I require.

I'm wondering if there is anything I can do to go back to the student plan, even a partial refund of the extra non-discounted cost that I should not have been charged for would be sufficient for me. If not, have I paid £49.94 for no reason, as I cannot use the software anymore, and I also cannot claim a refund.

Thank you in advance for any help.
