Hi. A while before Christmas, I ordered two books from Amazon. I waited a few weeks before sending a polite email to let them know that my order hadn't yet arrived. A day or two later, the books came .... followed by the same two books shortly after! By then it was Christmas and in the festive chaos, I forgot about the doubled order. Now I'm getting emails asking if I received the order twice. If I say yes, they'll charge me again. If I say no, they'll chase it up with Royal Mail. I know I should be honest, but then I'll be charged twice. It wasn't my fault that they automatically sent out more books though, rather than chase up the original order. What to do? Thanks!
