Unacceptable Service!

I have been a member of Sizwe since year 2000. I have always had excellent service until now! On September 6th this year I was admitted to hospital & I am still waiting for Sizwe to pay out! I have sent emails & have made numerous calls but they never get back to me! I have been calling every Monday without fail (at cost to me) hoping they will sort out my account, I ask for reference numbers & when I call back the next Monday no action has been taken! The staff at the call centre are most abrupt and unhelpful (They even sound too tired to speak) and extremely unfriendly! My hospital stay has not been paid in full, Lancet Laboratories not paid & 2 accounts for Dr A Naidoo not paid but yet I have been paying for this service! I have spoken to a lady named Grace who has promised she will put a request for me but to date nothing has been done. I also have a outstanding account for Dr Barnabas which I'm owing R1500 as I was just told the treatment is not covered but in the years preciously have never had to pay a rand. I am an old pensioner, where must I find this money as medical aid is always increasing but the benefits seem to decrease! I am a most dissatisfied customer.. I had to catch a taxi into town yesterday by myself! I will say the receptionist & consultant Thandeka Zungu was very kind & helpful. I am so stressed & tired of this more than disgusting service from Sizwe. I have been paying for full budget so I am rightfully fully covered for everything, especially my hospital stay so this is unacceptable!!
