Incorrect Debits

Hi, please note I was offered a promotion for the Vitality benefits on a 3month trial basis, when the 3 months was completed I received a call from an agent who wanted permission to go ahead with the Vitality which would cost me an additional of R400 plus per month in addition to my premium, I respectful declined and that was that, upon checking my payments I noticed that from December till current I have been charged for this benefit which I declined, I want to refunded for all of the premiums paid for the Vitality benefit asap. This was against my wishes and ********. Should I not receive a call today I will be referring this matter to the Ombudsman.
