Call centre cannot assist me to get my membership active

I called Discovery on Friday 5/01 as well as Saturday 6/01 because the amount they tried to deduct from my account was incorrect. I explained to the people I dealt with that my husband should be removed from my medical aid, which I called in for the 21st of November already. Two different people told me he is still on as a member and they couldn't advise me as to the amount needed to pay to get my membership active. After holding for a long time amd being put through to the finance department with no success I am seriously considering just leaving Discovery at this point.
