Cloud offer access troubles

I bought 3DEXPERIENCE ENGINEER for Students cloud offer, now quite more than 3 weeks ago. I have been sending sms for help and no solution, just delegating me to someone else. The purchase order number is ORD194002334904 with connected email: joan.pons.pons@estudiantat.upc.edu
 

I have received the get started mail, but when I try to log in, the message "Acces denied" appears.

Furthermore, I need to solve this situation now, is not possible to have these problems and no solution.

My number of the customer is: oi000258536. I have made some tickets, related with this same issue:
SR01276250-01
NTSR000099233-01

I tried to recover the password and tried to get in. Before had access denied message, now, username/password are not correct. I have also tried to change my password, but I do not receive the password reset email. Anyway, it's weird because I can log in to the dashboard, but not in the platform.

I would like to update the urgency to high!

 

Help please now!
