OUTSURANCE DOES A CREDIT CHECK EVERY FEW MTHS

Outsurance keeps doing a credit check without permission when they do a rerate on a policy. I dont know why they do this because every year they try and push up the premiums. Why they have to do a credit check every time, beats me. I am trying to keep my enquiries down on my credit profile, but lo and behold, every time they do the same thing. I want the entry removed from my name because it was done without permission.
