Bidvest insurance bad service

I canceled my Bidvest insurance extended warranty policy as I was not happy with how they communicate and their customer service . They have no sense of urgency and no respect for their clients they don't even bother to give you a response when they reject your claim had ti chase for a response received after 2 weeks insteadof there 48hrs promise. After I canceled I have been waiting for my refund as I had paid premiums for 2 years. My cancellation was done 2 weeks ago and was told that my refund would be paid in 72 hours another week has gone by and still I have not received my money. They keep saying they will call and send me a proof of payment. I urge anyone who has an insurance with them to reconsider because if they can not assist you speedily with small claims imagine the big claims. And bad communication and false promises
