IDP IELTS — Money got deducted already but no confirmation from IDP IELTS regarding th exam booking even after 48 hours

On 3rd January 2022, I tried to register for the IELTS exam on 12 February. Eventually I paid the mentioned amount via credit card. However the registration fee (14, 850/-) got deducted immediately yet it has been more than 48hrs and I have not received any confirmation mail from the concerned authority nor any information about the booking of the exam.

Kindly look into the matter at its earliest as I am running in a tight schedule to apply for the foreign universities.
I request the concerned authority to resolve the issue as early as possible
