Our sincere apologies for the problems you have encountered. Although our couriers are a separate company, they are there to represent us and have sadly let us both down; more importantly, they let you down. I will certainly pass your comments onto the couriers to try and ensure that this does not happen again.
We always charge cards at the point of despatch. Sadly with literally millions of items leaving us every year we are unable to have someone track each of them to see when they have been delivered to then charge the payment.
I have taken a look at your account and can confirm that the refund has been processed back onto your card today and if you have any further queries, please get in touch and we will be more than happy to help.
