iCloud support recorded call

Apple does not make such calls.

All such calls are scams from criminals attempting to steal your personal and financial information. The callers will often use number spoofing to pretend they are calling from a legitimate business. The correct course of action is to ignore the calls or hang up on them, repeatedly if needed. 

Avoid phishing emails, fake 'virus' alerts, phony support calls, and other scams - Apple Support

Absolutely it's fake. Apple will never call you. If they detect a security problem they will lock your ID and wait for you to contact them - that way you know who you are talking to. Never follow instructions or links in an unexpected phone call or email.
