Premium increase before anniversary date

<p>I have had my short term assurance with AIG since May 2016. Now 7 months later, I have received notice that i will be having a premium increase on the 1st of January 2017, which is 5 months before my anniversary date. I contacted AIG to ask them why, and was simply told that it was due to the number of claims they have had, but please remember that i have not claimed at all.</p> <p> </p> <p>This upsets me as how can I keep my insurance with them now? I can never be certain that I will only have an increase on my anniversary date, but it seems they may increase premiums whenever they need to.</p> <p> </p> <p>Very dissapointed and will be shopping around for quotes from other insurers.</p>
