Fedhealth Membership Cancellation

I have been trying to cancel my membership with Fedhealth since January and they are giving me run arounds. When I called them the beginning of Feb they said they cannot cancel because my medical aid is paid through my employer. And they promised that because I lodged my cancellation with a one month notice I will not be penalised for it But why didnt they mention that in the beginning? Thats a quention they need to answer. I contacted my employer and they gave me a cancellation document and I send it and they still did not get back to me. I called them around the 7 Feb and they said they received my documents and they are busy processing and should give them 5 to 7 working days they will send me a cancellation certificate but still nothing and today is 20th Feb. I have been trying to call from my cellphone and I'm on a waiting call until my airtime runs out. How long should I wait for Fedhealth to do this. I have already app**** and accepted on other medical aid and I dont need this kind of incompetence. I'm writting to hello Peter as my last hope to help me. I cannot pay two medical aids
