2 days ago I ordered an item for 70 and was told my payment had been declined, and to re enter my card details, which I did. It was accepted second time round. The next morning I had 2 order confirmations in my inbox, each with different order numbers . I cancelled one of them via an email to Amazon generated on their website. This morning there were again 2 order confirmations in my inbox and both items (identical) have been dispatched. So I guess they will be charging me twice (no money has left my account as of midday today). Is it too late to stop that happening? Is there a number i can ring? And if and when I do get both items and return one of them, will I have to pay postage (it's about 200g). Thanks for your help.
