Idp Ielts — Money deducted but slot is not booked

Hi,
Today I.e 5 february 2023 I tried to book my exam and payed for fees through debit card but after payment, message prompt saying payment is declined but money (Rs 15500) is debited from my account. I haven't received any email from idp regarding refunding or confirmation of slot. I booked there pen and paper based exam for 11 february 2023. The passport number is U7243938 and transaction number is[protected]. Please refund as soon as possible. I have to book as exam urgently as only 5 days are left for 11 february exam. This is not small amount to money so please refund it soon.
