Pineapple Insurance - unprofessional

I quoted for car insurance, the agent that assisted me (Gontse) initially quoted a lower amount (by the way they refuse to send you a documented quote they rather send you a link). Anyway we agreed on the quotation and took all my details and banking details, upon receiving the policy document, the premium was R400 more than what I committed for, I went as far as declining the debit order mandate on my banking app and they still send me SMSs that they will continue to debit my account via EFT, so in a way the insurance company commits customers to continue with their policy without my approval. I've demanded cancellation and they informed this is still under investigation and there's a 48 hour waiting period, I HAVE NEVER HEARD OF THIS.... This company is so unprofessional and still want to debit my account without my consent, why would they go ahead with EFT if I've declined the debit order mandate, WOW, terrible experience!!!!! I still have not received any cancellation confirmation nor documentation, I guess they want to take my MONEY
