Where is my Student Discount for Prepaid Unlimited?

When I ordered my SIM and ATT Unlimited Plan (Prepaid), I did it through student bean verification via https://connect.studentbeans.com/v4/hosted/at-t/us/ and it was made clear that starting from month 2 students will get a discounted price of $40/month for the unlimited plan.

However, after I got my SIM and activated it, it says $65/month, and after I set up the auto pay, I am still having to pay $50/month and the webpage said starting next month I will be automatically billed $50/month. Where is my student discount price of $40/month (starting from month 2)?

Please kindly follow up ASAP.
