iCloud hacked?!
I have received a call from a number 1-800-275-2273 claiming my iCloud has been hacked. Is this number real? I have not received any type of email saying this.
Such calls are scams from criminals trying to steal your personal and financial information. They use number spoofing to pretend they are calling from a different number.
