Shocking service Vitality!!!

As a dependant on my husband's medical aid, I am supposed to be included in the Vitality premium that is paid monthly by him. For 17 years Discovery has been debiting my personal account and my husband's account for the Vitality premium. Thus, a double payment! I phone Discovery daily to resolve this issue and have collected hundreds of reference numbers for the enquiries with no further response from Discovery to resolve this issue. The customer service is shocking to say the least!!!!
