Someone on Facebook is harassing me indirectly, how can I report it if I’m not a member? [closed]

I am not now, and do not want to be a Facebook user. Someone on Facebook is making multiple comments or posts giving my personal cell phone number and some WhatsApp page, and saying that I am an immigration consultant, possibly named Lillian, who can provide a job in Canada and assistance with immigration, for people in Kenya. (Just to be clear, I am none of the above.) As a result I am getting multiple phone calls from Kenya daily, most at very inconvenient times.

I have looked at the Facebook “report impersonation” page and their “report defamation” page, but they both require a link to the offending Facebook profile. I can’t get that link, because by the time I can find the offending post, it has been moderated out of existence (presumably because it’s “commercial”), or else I simply cannot see it because it is targeted only at Kenyan users. There does not seem to be any way to report this sort of ongoing harassment of a non-member.

Is there some recourse that I’m not aware of? Is there some way to reach a Facebook contact where I can get this corrected?
