Premium increased without my knowledge

I am sitting here for the second time writing a complaint on Hello Peter for Discovery Insure - and I have only been with this company for 2 months, So that means one complaint every month. I cannot understand how pathetic an insurance company can be.<br> <br> When I took out the policy and explicitly mentioned that I have a secondary driver, however I did not have the ID number of the person at the time. When I called in later to provide the ID, suddenly the premium changes. The worst I only see it when I get debited.<br> <br> I have logged and sent so many email - and to day no one has helped. I am convinced that moving to this insurance was a mistake.
