Was I Cheated?

Tweet

More than one week ago,I booked an MP3 on line. At first,the seller said that I can pay the money after I receive the MP3. But after I told him my address,he told me I should pay the money first,because I wasn't in their province. Then I paid the money through the bank card. And he told me I can receive it at most 3 days. Lastnight,I asked him why I haven't received my MP3. He gave me his boss' telephone number. So I call the boss. He told me he was so sorry about that and he wanted to receive my message what about the MP3's type and my address. Then I sent him an message,and add a sentence,"If you receive the message,please reply me,thank you!" But,no answer. Was I cheated?
