How to get the exam payment receipt?

Hi,

I hope someone can help me. I passed the exam last month. Now, I'm trying to submit the payment receipt to get the reimbursement from my company. On my PSI exam account page, there's no more option to print the receipt. I also contacted PSI a few times but they couldn't help me with that either. 

Is there another way to get the receipt? 

Thank you,
