Serious bad service and ******* Termination of membership and no proper excuse

I have been with Fed health for the past 5/6 years, last year I upgraded my plan the debit went off as per normal. Two weeks ago they advised they membership has been terminated. When calling them to find out what is happening, they advised membership has been terminated for ALL members, non closure of information was received. I send them all proof when applying for the medical aid all history was presented. I have paid my contribution for the last 8 months of R 11000.00 per month, now all of the sudden they terminate. I feel this is wrong as everything should be on their system all history of claims should also be on their system. My husband suffers from high blood pressure this was acknowledged to them, now they say it was not, hence I have this on email in writing. The broker that called me namely Wellworx still emailed me the confirmation of our telephone call where it clearly shows my husbands history. They left us now in the middle and not want to listen to anything we say just cancel the medical aid and keep the money we paid. I went for a medical emergency and we were not covered as yet (still on waiting period) we paid all of that out of our own pocket. Fedhealth makes promises, they are useless and do not want to help the members just push a button and you are history. If you call them the person on the other side can never give you information "with the underwriters". My question is should this not be done when you apply for the medical aid NOT halfway through paying contributions already!!!!!!!!!!!!!!!!!!!!!!!!!! Today they send me a mail, now all of the sudden it is my history and not my husbands, somewhere someone is not doing this correctly. Very disappointed, always used Fedhealth but I think they are loosing the good service bracket. No one from underwriting can talk to you as "they don't take calls" how the hell do you need to sort this out if you need to speak to a consultant that cannot tell you anything. I need to know if someone has a higher authority contact I can send my disputes to as sending them to Fedhealth email address is not going anywhere. Member number ***, I will not leave it as this as all of the above and every communication with Fedhealth makes NO SENSE
