Received a call from Apple about security breach. Please acknowledge that this was APPLE!

I don't think so. Most likely a scam/phishing attempt. IGNORE it.

No it was not Apple. Apple will never call you unless you initiate contact with them. Take a look at this.

Apple does not make such calls. Ever. Hang up on criminals.

No, that was a scam and would have tried to gather personal information in an attempt to steal something from you.
