Cannot purchase Student License

I have to use Matcad on one of the modules of the university course i am doing. I went to purchase the student license and it states that the estore is undergoing maintenance but it will provide me with prime 10 free for 30 days. So i was emailed a link, downlaoded prime 10 and then after being told i had to create two accounts, one on the web and one on the app it eventually got the license and full functionality. I then get an email stating my trial is running out and to click the link tp purchase a student account. I click it and it asks me to enter details and someone will contact me. This has been over 2 weeks now and multiple forms filled in for contact have been ignored and no one has contacted me so i can purchase a student license. I am at a loss. ALl i want to do is keep MatchCAD going for more then 30 days as the module is 3 months long! BUt for some reason PTC seem impossible to actually purchase their product.

Does anyone know how i can purchase this license or how I can make a complaint (or is it even worth complaining as every other contact form regarding this issue has been ignored so far!)
