The majority of support enquiries we receive about this issue is the result of the bank displaying the authorisation on the statement, authorisations are part of normal bank processing and are automatically resolved by your bank. Authorizations are removed as soon as the actual charge is applied however some banks can take a couple of days to resolve them.
In most cases banks inform the customer about the authorisation with a visual hint, such as using 'pending' in the description. Authorizations ensure that there is enough money in your account before any funds are transferred.
