Be sure before you go with dotsure

I canceled my insurance with budget because I was given a better quote with dotsure. There was a misunderstanding about the address and my premium went up by R1000. I even changed my building cover to dotsure and now the schedule shows the wrong building address too. I canceled all my other insurance policies because I thought I would get all with one company. Now I can't afford the new premiums because they are higher than the other policies. I feel so overwhelmed because this is my first car and I want to have the best insurance with the best possible premium. Now I can't afford it and I can't switch back. Please help me.
