BAD SERVICE VFS SOUTH AFRICA

I have given VFS SOUTH AFRICA a rating of 1 but to my mind that deserve a rating of -10 .At end of OCTOBER 2015 i submitted my documents for PRP CERTIFICATE...After waiting in line for 3hours ( had a supposed appointment ) after almost 4YEARS & paying R1450-00 I still have receieved NOTHING FROM EITHER VFS OR DHA...KEEP PHONING VFS OFFICES WHO KEEP SAYING THEY WILL ESCALATE MY APPLICATION. ...THINK IT NEEDS MORE THAN ESCALATING. ...NO-ONE AT DHA PREPARED TO HELP ME....WHAT DO I DO ??????
