Had a call from a male with an Indian accent claiming to be from BT technical support. He tried to convince me that I had a problem with my PC by asking me to view the Windows event log. (See https://en.wikipedia.org/wiki/Event_Viewer for details of this scam). As I was using a junk PC which I boot whenever I get this type of call I went along with the scammers. When I told the guy's 'supervisor' that I was going to publish a recording of the conversation on Youtube he dropped the call. (Despite the number being displayed as if it came from a UK number my caller id display also said it was from an international number. Sophisticated scammers often change the 'presentation number' shown on your phone).
