I preordered iPhone 6 Plus Space Gray 64GB on 9/12 by phone, didn't get email confirmation. 10 days later, I talked to a support, he told me my order "wasn't completed and went through fraud"(preorder went through fraud). Today, I suddenly received an iPhone 6 Plus Space Gray 16GB, not the one I ordered and clearly that in-completed order was completed.
I've made another order online last week. How can I return this iPhone which I haven't paid for and cancel this order? Or, can I exchange it for a 64GB device to complete my second order?
Thanks
