You should have received an order confirmation email, in that email is a link to My Account, from there it has your order and you can cancel it there. I know cos I've contemplated doing it myself because of the wait
I ordered on the 03/02 and shipment was due today 13/02 but got email saying its now 27/02. Spoke to customer services and they've said the same. I don't think they know when they're coming in, very frustrating as I had built myself up with excitemen...
