I still occasionally get phone calls from 'Microsoft' telling me that my computer has been invaded by viruses etc. Annoying but an excellent opportunity to exercise freedom of speech.
I have a friend without a computer who managed to prolong such a conversation for some ten minutes before revealing that fact, much to the caller's annoyance!
Do what I do. I say "the computer belongs to my brother, he's upstairs. I'll go and get him, don't go away".
Go back every 45 seconds and say "he's just coming, hang on".
Then leave the 'phone on the sofa and let the prat just hang on for as long as he is stupid enough to hang on for while you carry on with what you were doing!
Just remember to put the 'phone back at the end.

Use your mouse to 'hover' over site links or email links and you see where they really are at. Anything unfamiliar is dodgy.
You already see the email is cocacolakids@.... wasn't that a good enough clue???

It was only after reading this thread that I thought to ring them - out of interest - to check if the email was genuine. It was, and I expressed surprise that they'd included a link. Not that there's any security risk when the message is genuine.
I used to get bombarded with false emails from 'high street banks' starting 'Dear Customer', even though I didn't have an account with them. The web and email addresses looked genuine, and the website would have looked genuine too if I'd clicked on the link. I'm not sure whether these operations have been shut down but I haven't had any such messages lately, not even in my spam folder.
