Facebook is having it's way with my phone log

[AC Question]

I am confident that Facebook is getting it's hands on my phone log and/or possibly my Google contacts. How can I prevent this? And I already checked with FB's privacy settings, no mention of it there.

I called a moving company from a print ad (they have no website). I entered him into my contacts. We spoke and texted that's it via my Android, Galaxy Note 3. He is now on my "people you may know" in FB. Worse my first and last name are on his FB.

This has been happening to alot of people on dating web sites (me included) but I couldn't tell if maybe the sites and Google had some arrangement but now I realize it's got nothing to do with internet contact. FB is getting the relationship straight from my Android and it's pissing me of. Not enough however to sell my FB stock, which has dome nothing but continually go up in value

Any ideas on how to put a stop to this short of closing my FB/Google accounts would be appreciated.

Welcome to Android Central! How current is the Facebook app? Does the phone have any preinstalled Samsung Facebook interface (like a social hub)? If so, that might be syncing with your contacts. Go to Settings>Accounts-Samsung, and see if Facebook is listed there. You could also go to Settings>Accounts-Facebook, but if your app is current, then there shouldn't be a contact sync option there, since Facebook took that function away from the app some time last year.
