https://monitoring493.gq/iOS-3x73support4190.com/
They told me to install Zoom, which is a remote business meeting chat and calling system. He said that $100 for security and support, and there’s an offer for an iPhone X for only $200. At the end (they told me to buy an iTunes gift card), I messaged him this link Phony "tech support" / "ransomware" popup… - Apple Community and told him that he’s a scammer. He just hung up.
Here's part of the chat:

The bottom part is just the link to Apple Discussions. He didn't even say anything after telling him that he's a scammer.
Nice!
@atomicdragon136#35558 Nice!
@Logim#35563 I at first thought they would tell me to install Teamviewer on my iPhone (yes, Teamviewer has an app for iPhone). Well, the scammer didn’t need remote access to my phone. But I wish he did.
@atomicdragon136#35595 Yeah thatd be fun to mess with him on the screen share.
@Logim#35556 This is the new link https://website033.ga/iOS-1x76support0207.com/
@Logim#35648 How do you find out?
Keep calling them and swearing at them in hindi and they just swear back at me and hang up lmfaooo
Website apparently got shut down
@RatExterminator#35669 But the number is still active. When they picked up the call they said they are from apple care. They represent as they are directly from Apple. They are from India
@atomicdragon136#35654 Go to agor.io and after a few tries it will reroute you to their link.
