Facebook free 2 platinum

Please fix this Cause I need the 2 platinum for xp
I liked it akready but the platinum didn't add in my account
Then after I restart the game it resets and I tried again a few times but still it didn't get in my account https://uploads.tapatalk-cdn.com/202...35ce44dfb4.jpg

Have you done it previously on a different account? I think a particular facebook account can only claim it once.
