*****ULANT ACTIVITIES BY DISCOVERY VITALITY

I have sent emails to Discovery Vitality about why they are trying to debit installments when I do not have a medical aid with Discovery and also trying to debit from a bank account that was closed. I am trying to fathom why they were trying to debit installments from an old account for over 5 to 6 months now when my banking detail was chenged with them about year or so ago.I am still waiting for them to reply or contact me and they have not done so.
