Apple Icloud scam call

I received a call on my iPhone, the caller ID said Apple Inc. I answered and the robo voice said my icloud account has been breached, and to press 1 and remain on the line. I pressed 1 and a person came on. He said he said he was from Apple support. I just listened, I thought it may be a scam, as Apple never calls.

The person knew my name and said my account was breached. I was quiet, and he eventually hung up.

After her hung up, I looked at the caller ID and it identified the caller as Apple Inc. I redialed the number and it called Apple Support --> 1 877-412-***3. I looked up the number on the net and one webpage said it's a scam number. How can the scammers know my name and number. I never use this number. And they use Apple's support number to show that it came from Apple Inc?
