Course purchased but not received anything

Hello. I purchased " Introduction to Physics-informed Machine Learning with Modulus" for $30 (order #63121) but I have not received anything after 10 days. Despite contacting customer service from different route, I have not yet received any response from them.
Please help me access the course.

Hello @davood,

I checked your developer account, and there is no history of a course purchase.
Where did you make this purchase?

Thanks,
Tom

Hi, Yes, the problem is I cannot find my course anywhere.
I made a purchase on Deep Learning Institute.
Can I forward Order Confirmation email from Nvidia to you directly?
Best,

Sorry, I don’t have access to the payment system.
This will require a DLI engineer to assist.

@tdahlin can you please help here?
