32% Increase in premium after 1st year

So one year after joining Hollard Insurance for a competitive premium i get notified of a 32% increase in my monthly premiums. The call centre explained that it's due to various factors, including more expensive parts - which i find hard to believe would justify the large increase - the vehicle is a stock standard Toyota...<br> Even worse was the fact that the Call centre agent advised me that i can only ask for a review on the premium after the increase premium has been deducted. Further that it doesn't seem to bother them that i'm forced to obtain quotes from other suppliers - no customer retention. This seems like a devious way to get new customers, and then punish them after a year of no claims and a decrease in vehicle values.
