It can vary a lot depending on how long it takes PayPal to notify us of the transaction. If the transaction in PayPal is marked as "Completed" then it shouldn't take long. If it's pending for any other reason, such as security checks or eCheque clearance then it can take longer.
Best thing to do is Contact us if you have any further questions and provide details of the transaction there.
We can't provide help for payment/customer account issues on the forum and deal with them in public, so please contact us if you require further help on that particular subject
