Sizwe take every month, but cannot pay

I have 2 claims that have not been processed from January 2017, I have the reference numbers and have been told to call back in two weeks, this has been happening every two weeks from May 2017, I have called back over 20 times with no joy, have emailed call centre agents and team leaders but no help. All keep hearing is that there is no one in processing that deals with customers directly. I have paid over R20 000 to doctors and hospitals. I WANT MY MONEY BAC**** and am sick and tired of the excuses. Please DO NOT ask me to email queries as no one responds!
