I Pre ordered an apple iphone 56 days back from their official website. They even gave me a confirmed registration number in my mail. But till now I have not received my iphone at my home. I am very upset about it. I told their customer care executive about this problem. He asked me my registration number. I provided him my registration number. He told me that this registration number’s product is already delivered and we can’t do anything now. Where can I complain about pre order iphone 4?
