Idp Ielts — Have not received confirmation letter after booking exam

Address:

Gwalior, Madhya Pradesh

Hello, Harpreet this side, i want to notify that i filled my ielts exam form yesterday along with my 2 friends by our mobile phones.
After filling all the details, we proceeded towards paying the exam fees of 16, 250 through UPI via Razorpay. The payment got debited from our bank accounts but as soon as we reached back to the IDP website, it started showing 404 error . Message from bank account came regarding the debit but we haven’t received any confirmation email or message from the IDP regarding the booking of exam .
What is shocking is that the same happened with three o[censored]s .
Help us with this ..
we also have reference id, details and screenshots of payment.
