GTA 4 stats are not updating to socialclub site

I don't understand the reason why my current stats are not updating to my socialclub account.I mailed many times but Rockstar support was failed to reply me.

I always play GTA 4 while connected to internet.Linked game for windows-live and sign in inside game too.And i also re-linked the gamertag,but no use.There is no problem with Max payne 3.

Can someone help me here.You might already faced such problem so hoping for solution.
