We'll look into this straight away. Please can you tell me your Account Ref so I can look at your particular case - you can get this from the Account Details page.
We use an online service for withdrawals which should minimize fees but still ensure fast processing. Something must be going wrong there. If we confirm that you have been overcharged then I will ensure it is credited back to your account.
