Received this call (on call waiting) while on another call. Person identified himself as 'Simon' calling about PC problems; when asked, he said he was with "PC Care". Said he was calling because I'd hit 'Send a report' when my computer would lock up. I asked for a callback number, this is number he gave. When I tried returning the call, I got a recording that 'call could not be completed as dialed'. Tried several times and got the same recorded message.....stinks like a scam to me!
