No Feedback and Shocking Communication from VFS

Can you please assist, my visa was wrongfully rejected and once reviewing at VFS it was sent back to Home Affairs. VFS promised me they has escalated the matter and I would hear back very soon. Needless to say I have not heard back and am chasing up VFS daily and getting no response by the manager at the Rivonia branch. My current visa expires in the next few weeks and this problem needs to be escalated and dealt with immediately. The lack of communication is absolutely shocking - its like they do not understand the effect this has on people apply for visa's!!!
