Repeated phone call to my house about a security computer breach on my iCloud account.

No, Apple will never initiate contact with a customer. It's a scam.

I find this an effective defense:

I too have had nine phone calls today! Only half of the recordings were available for me to hear. I didn’t get who was calling. Finally the 9th time I picked up. They announced that my iCloud account was breached, dial 1 to talk and 2 to hang up but before I could do either, I was disconnected. I assume this is fraud especially calling with an unknown number!

Yes, definitely.
