Unauthorized debit order from innovation group

I have 2 policies for car maintenance with innovation group so I called them last year September and spoke to the lady called Linda and asked for 1 account settlement amount as I wanted to settle it and she told me I'm only left with 1 instalment and de following month it went off den it was settled. To my surprise after 5 months they went back to my account for that same account and same premium and when I called I was told that its not yet settled n I asked to speak to de manager and I was putted on hold for 10 minutes I ended up dropping the call.
