Caller: I called the man called Peter

I am living in Sydney, I purchased an electrical wind instrument via EBay 3weeks ago. I found the instrument makes funny sound yesterday and I tried to found a direct phone number that I wanted to speak to someone directly on Google. And them a number of (08) 6245 7237 popped up. I believed that was a number belong to EBay service. And then I rang that number and a man called Peter answered me. He asked me whether I want to refund or replace it. I said I want to replacement. And then He asked me which method of payment I made on purchase and I followed his instructions gave him my detail of credit card. I was very upset about my instrument and did not realize that I am in trouble. And in the end he used my card purchased some thing from some where called ALIEN COMPUTER.
