Ridiculous increase

After being with Dial Direct for close on 15 years, I am incredibly disappointed with the rate I am charged since making a change this year (I moved 4 km's down the road and received an increase of R200 on top of my previous premium). I have an impeccable profile with only 1 claim for a windscreen over the duration of cover. I am told there is nothing that anyone can do - that no manager was able to look at my profile to see what could possibly be offered in order to keep my business. I have small household contents and a vehicle which is more than 3 years old and am being charged R 1 000 a month. This feels absolutely ridiculous and as I told the consultant, I will be looking elsewhere
