THIS IS FOR SURE A SCAM!
I called Apple direct (the REAL Apple customer service). THIS IS A SCAM, THIS IS NOT APPLE CALLING. Apple explained they don't have the capability to know if any Apple devices are having problems, be it software, hacking, etc. He explained further, when someone with an Apple device is having troubles, the owner of said device will contact Apple, not the other way around.
DONT ANSWER THIS CALL, doing so just opens up the door to more calls from these scum people or they sell your number and expect double + scamers to call you.
Called Apple support. They are going to play with them and then ruin them. I toyed a bit with them too! Read out some long email address and kept changing it by one letter for 4 minutes. Gave him about 17 different emails. He still didn't get it but made me feel vindicated then put him on hold. The hold button was blinking for 3 more minutes.
