Just to be clear...

You're absolutely sure, 100%, this is Meta employees themselves calling you? And Meta sending you e-mails?

Not spammers, of which there are many, and they get your contact info from all sorts of places? And which often lead you to believe they're Meta when they're really just scamming you or trying to sell ad placement consulting/optimization services?

Because with "multiple" calls and emails... this sounds like 3rd-party spammers, not something Meta does. And while Meta has been loose in the past with walling off information internally (to put it mildly...), it's not like they sell your contact info to spammers or anything (simply because it's not worth the effort, the money's way too small for a company of their size). Third-party spammers, on the other hand, will get your personal info from anywhere and everywhere.

For you to make a credible claim that Meta is using your 2FA contact info for marketing, you've really got to be sure that it's 1) actually Meta contacting you and 2) that they got your phone number specifically from 2FA and not just from looking it up publicly the way salespeople do.

Indeed it is. I too thought that perhaps it was a scam. But the call was followed up by an email from business.fb.com and per their Help Center, it is indeed from Meta https://www.facebook.com/business/help/372703956148310
