Sorry for the inconvenience !
I see you have an Adobe account with the same email as with forums.
After checking all the details, I found that Creative Cloud Students and teachers is not available in your region.
You can purchase the Creative Cloud photography plan for 11.99 € .
Unfortunately it would not be possible to get you back to the previous pricing, still kindly Contact Customer Care for any alternative.

Hope this information is helpful !
Fell free to update the thread in case of any other questions !
I already know that I can not get student subscription, but it is a bit late now.
What I have asked about is: why should I pay extra money because of Adobe support mistake?
And not only extra cost of the plan, but also start over my 1-year "contract" of obligation?
