Decline insurance due to incorrect facts

I decided it may be appropriate to move householder insurance to Outsurance as my cars are insured with them. I spent 20 minutes providing all the details including a burglary to the value of R450 000 in February 2016. They then came back to me basically accusing me of lying stating I had had a loss of R450 000 in 2016 AND ALSO 2015!! Where the f... they get their information from is unclear as the consultant couldn't tell me. If you have had any claim whatsoever they treat you like a ******** but to accuse you of claims that never happened is shocking and extremely annoying. What a waste of time and effort and exceedingly frustrating at the same time. Charlatans.
