Hi. The Department of Social Development has been silence about the possibility of an early grant payment for the month of January. While it seems like the grant funds are available in some beneficiary accounts, some reports that their balances are still at R0.00 If you really have need, the best you can do is to try and check your balance either by dialing *120*69277# or at an ATM.
Edit: The latest hear-say is that the social-grant will only be available for collections on the 1st of January 2016 - and no, no beneficiary have been confirmed to have received the January social-grant as of now.
