Hello everyone,
I really would like to know how to fix this problem,
Well, I invited some friends using the Facebook button which says you get 5,000 points for every recruit. One of my friends did accept the invite, installed the game, created an account, and started playing all which happened yesterday. I gave it a 24 hour rest thought maybe until the servers refresh and get data organized. But unfortunately, I have just checked and still no points added.
If anyone could help, I'll be much thankful.....

Thanks in advance all...

sometimes it does take a little longer than 24 hours.
