Outsurance not paying up!!!

I was not happy with the insurance quote for my motor vehicle I received from Outsurance, and they could not explain the ridiculous high premium. I cancelled my vehicle insurance and Outsurance rreceived a letter from my new insurance company stating the fact that are my new insurance company. Despite that, Outsurance still have my premium deducted, an amount of R3449-15. I personally contacted them, and was assured that they will immediately reverse the deduction. To date, two weeks later, I have not received the payback. My new premium is R1000 per month. Outsurance quoted me more than R3300-00 When raising the matter, they had many reasons why I do not qualify for the R400 rand bonus Outsurance promised to clients if they cannot beat their quote!!!!
