Refund Me

I ordered an item and the following day wanted to add another item. There was no where to amend and no information or anyone to speak to. Extremely frustrating!!!!! I cancelled the order as it showed it was still to be confirmed (a Sat morning) with the reason that I was placing a new order with another item. What a surprise when both orders were delivered to me and the 1st order collected again a few hours later. I have been refunded the item value but not the courier fee. It is not my fault your system is so hard to use. I finally managed to actually log a query and after an automated response where I said it does not help (it did not) I have heard nothing more. I want the courier fee refunded ASAP. Put an option to amend orders, very surprised you do not have this!
