We only pre-authorise your card and the block is usually released 30 minutes after an order being cancelled.
First, please double check that the money has definitely left your account (check the balance has changed) as online banking can look like there is a minus transaction when there isn't.
If the balance has changed it could mean that the bank hasn't released the transaction correctly. To correct this there are a 2 options:
1) It will release on it's own, usually the next day or definitely within 7 days.
2) Send us an email to email@example.com explaining that you cannot wait for the block to be released and that you would like us to help speed up the process.
If you are still having problems, you can give one of our customer service team a call on: 01625 800288.
