Misrepresentation and dishonesty

In April, I contacted Bidvest for tyre insurance and exhaled to the agent that I just got a quote for R10000 for all 4 tyres. She then sold me tyre insurance and not once did she disclose that this was for accidents cover. I have comprehensive cover on my vehicle and did not need additional accident cover for tyres. I told her this is purely for when I need and have to change my tyres. I was mislead and sold a policy I did not need. I even asked her about the waiting period and she said none what so ever. Now I submit a claim after my car service for two tyres to be changed and I’m told this is not covered. Immediately lodged a complaint, and requested cancellation and my premiums back. They still went ahead and debited my account this month, and now I’m being ask to complete long documentation for the recording. This company is not reputable.
