ACCA online registration

Hi,

I just now made my online banking payment to ACCA registration fees and two paper exam fees.
After i receive the acca acknowledgement email, i realize that my bank’s money not yet being deduct and i cannot access to my acca again as it will jump me to the REGISTRATION ENQUIRY, After i typed in my registration number, it will show
“Application Documents Scanned”.

This means i just wait for the ACCA reply whether i got my exemption and registration success or means i need to pay again in order for them to process my registration?
But i already receive the acknowledgement email from them?
I wonder why my bank account remain same amount?

Thanks for the answer in advance.
