Bad service and running of system

I’m so disappointed in the horrific service that I’m receiving from Fedhealth. I was considering moving medical aids due to receiving horrible service with two seperate incidences in 2018. Thus I send my letter to terminate my contract for end of Feb 2019. Not responding to my email I eventually contacted them telephonically they said I need to email again. Once I found out they amalgamating with another scheme I decided to stay a Fedhealth member as I have a 1 and 3 yr old to think about. I contacted them telephonically again to say I no longer wish to terminate my contract and even with drew money from the vault. Now I received a letter to say my contract is terminated. When I phoned them 13/3 they stated they have no confirmation that I said I want to stay a member even though I have a ref and they have the cheeck to say I must pay the money I took from vault even though I haven’t used anything. My 1 yr old is ill now I can’t go to the dr because of this issue and error on this side.
