Money debited without any consent

On the 22nd September 2020, Miway debited my account with R1089, which is not the premium i pay on a monthly basis. When i phoned to query the transaction, I was told that it's for an additional cover that i took last year October and they (Miway) have not been debiting for almost a year. So when they realize that they have not been debiting, they decide on their own to just take money off my account without any consent. I phoned to advise them that i DO NOT want any additional covers, but they still felt it was ok and normal to included the additional amount on my premiums again this month. Someone is clearly not doing their job. I have been phoning almost everyday to follow up on the refund to no luck. The last time i spoke to a consultant that was extremely rude. If anyone was considering Miway as an insurance, i would think twice.
