Horrible service - Discovery gap cover

I was with discovery medical aid and their gap cover which I terminated 2022 February 28 was the end date. I have received my termination letter, medical certificate and one of their clause was that if I terminate the medical aid, the gap cover falls away despite this, and I'm endless calls to inform them that I'm changing medical aids thus terminating theirs, Gap cover to date is still debiting my account. Now I have two gap covers, my new medical aid gap cover and discovery gap cover despite being promised that it was cancelled numerous times however, every month, they still debit my account making me incur bank changes. Horrible service, horrible staff and definitely a good reason to have left them.
