Hi CHICHIBAILBONDS,
Welcome to Apple Support Communities. It sounds like you're seeing a pop-up window in Safari on your iPhone indicating there's an issue with your device. I also see you've called the number and discovered it wasn't Apple Support. I can see why you'd reach out about this; I'd like to help. What you're seeing is likely a phishing attempt: Avoid phishing emails, fake 'virus' alerts, phony support calls, and other scams
In order to stop this appearing in Safari, you'll need to attempt to either close the tab or change the web address:
Tap to view all your open tabs. Then do any of the following:
- Close a tab: Tap in the upper-left corner, or swipe left on the tab."
Use tabs in Safari on iPhone
If you see an annoying pop-up in Safari, you can go to the Search field and enter a new URL or search term to browse to a new site. If you don’t see the Search field on your iPhone, iPad, or iPod touch, tap the top of the screen to make it appear.
Some popups and ads have fake buttons that resemble the close button, so use caution if you try to close a pop-up or ad. If you're unsure, avoid interacting with the popup or ad and close the Safari window or tab."
How to block pop-ups in Safari
If you're having trouble with either of those steps, you can also clear history and website data from your iPhone: Clear the history and cookies from Safari on your iPhone, iPad, or iPod touch
If the alert you're seeing is occurring outside of Safari on your iPhone, please provide the following details:
Where on your iPhone are you seeing this alert?
What is the exact message you see?
Are you able to restart your iPhone?
Best Regards.
