Withholding information and wrong information

The worse people to deal with its been more the 3 weeks that I asked them to call so on the 4th after I called and shouted they called me back they sold me a product did not disclose all the information sold told me I would pay r5300 for medical aid , gap cover and medivault and then when my 1st installment went off it was not that at all I paid kept quite so when my medivault was depleted kalin from wellworx assured me it's fixed and my medical aid amount will not change I even called in to confirm so my medivault got done then he said I will have unlimited access to GP visit so I when to doctor and to my surprise medical aid didn't pay so I call the medical add no they say I must hit the threshold I was shocked I needed to get my doctor paid so I activate r4000 to reach the threshold. they say I must call wellworx did on so many occasions so they listened to the voice call this lady dares tell me I activated the r6800 medivault the more I say I only activated the r4000 the more she is trying to cover her self I keep on asking for the recording and till now nothing she was suppose to call me on 5th of April and she didn't I have given them 2 options I want a refund and the guy that sold me the incorrect product will be layible for the rest or I cancel with immigrate effect and they sort the medivault out
