In Australia there is a very clever scam going on at the moment. When your email stops working, you may get a call from someone claiming they are from ‘Apple Support.’ It may be a polite greeting like ‘Hello this is Mary from Apple Support and we’ve noticed you’ve had a problem with your Gmail on your Apple Computer. This is a problem we are working to fix. Are you at your computer now…’ etc. This happened to a relative of mine and it was soooo convincing that I could not initially convince them that it was not Apple! To verify it we asked for a case number from the person, then rang Apple support, to find there was no such case number.
