Looks like there is a current scam/phishing hack going around and it seems pretty convincing. It’ll look like Meta Support reached out to let you know that your page has been disabled and you need to verify your account.
Same here, last week our business page got a message like this. I quick did a google search and found that it was indeed a scam. I’ve gotten one more message like that since then on our other business page and simply deleted it.
