IDP IELTS — IELTS Test Fees Online Payment

My Name is Dhwani. I tried registering for my Computer Delivered IELTS exams from IDP website from Ahmedabad West Zone and made an online payment of INR 14, 700 via BHIM UPI and the amount got deducted from my Bank Account but the IDP site says that the payment was rejected by my bank and that the registration could not be completed.

INR 14, 700 is a huge amount for me and I would like to get that back right away. This is not something to be expected from IDP.
