Divorcing cheating husband results in high premium

I informed OUTsurance that they needed to update my policy as I will be getting divorced end of the month. They wanted to increase my premium with more than R400.00 because I was no longer married. In the end, after holding on for about 20min, they stated that no worries, nothing was increased. When I got my new schedule, I noted that despite their promises, my vehicle and content premiums were higher than my 'married' premium. I don't think that this is a good example of treating customers fairly. I have been a loyal customer since 2009. Joined them before I got married, but don't think I should stay with them.
