this guy faked a british accent, claimed that I called iPhone then corrected himself, "icard" and said that there was a fee incurred on making such a call to "icard". I said that he must have the wrong number and then he called out my phone number (which was mine) and said I have to pay up.
He said, "I think it's time you pay up!" I said, "No, I think this is a fraudulent call" and hung up
